  • The first part of the mid-season finale. A great episode which only suffer from only being the first part of a bigger picture.

    It's really hard for me to review 'I know what you did last summer' without taking consideration of 'Heaven and Hell', since the two of them are so closely intertwined that it is almost impossible to discern them. The only possible difference I can make is that 'I know what you did last summer' is like the theoretical preparation for the factual execution that will be fulfilled in 'Heaven and Hell'. And, of course, 'I know what you did last summer' is all about the necessary background - mythological both in concern to the show and the over-arching lore of Demons and Angels - that viewers needed half-way through Season Four.

    As such, in this episode we discover what happened to Sam while Dean was in Hell. And as we see him destroying himself in a downward spiral of guilt and desperation, coupled with too much alcohol and a reckless attitude bordering perilously on suicide attempt, we get a chance to see how Ruby cleverly sneaked inside his sorrow and anger, making him believe that, if not reparation, he could at least have revenge over Lilith. On a side note, I must add that - already knowing what happens in 'Lucifer Rising' - makes this episode even more interesting to re-watch, because this way we can satisfyingly see how well every piece falls right into place.

    'I know what you did last summer' introduces also Anna Milton, which was clearly intended to be Ruby's counter-party, but turned out a lot more fascinating than her. Julie Niven is quite good in portraying her, but it was the revelations Anna had that made the whole storyline all the more interesting: Anna knows about Lilith and the Seals, she can hear the Angels talking and knows how Dean was saved from perdition. It's obvious that the Demons want her, but when the episode finish with the Angels revealing that they want Anna dead, 'Supernatural' - thanks, and it should come to no surprise, Sera Gamble and one other of her wonderful scripts - shows once again that its strength comes from the moral ambiguity that lavishes every character, making them not only more believable and consistent, but also more compelling and riveting, not to mention that this ambiguity adds another layer to what was already a surprisingly complex, flourished mythology.moreless

    I really, really, really want to stop gushing about this show. It's becoming embarrassing; really, it is. I mean, how many times can you heap reams of hyperbolic praise on a television serial's scripting, production and casting before it starts getting a little tiresome? Before it starts looking like you're secretly blowing the production designer? Which I'm not. Honest. I just can't criticise it though. I can't bring myself to lie. The truth, you see, is that Supernatural is the most consistently well made and entertaining series on TV right now and 'I Know What You Did Last Summer' is the perfect example of why. We've got significant character development, a fresh narratalogical approach, acres of action, violence and sex, damn fine performances from all involved and, crucially, a plot so hot and juicy it'll make you do a special dance in your pants. Sera Gamble's script is densely packed, taking the explanation of Sam's current status as its central aim but weaving a whole host of other exciting revelations around it (Dean knows a lovely bloke called Allister, played to eerie perfection by the brilliant Mark Rolston), while also predicating the whole thing on the uncovering of the importance of a fantastic new character - Julie McNiven's beautifully fragile Anna, who hears angels and demons talking in her sweet little head. This episode feels exactly as it should: like a forebodingly important piece of a gargantuanly terrifying whole. And what about that cliffhanger, eh? Jaw, say hi to the floor for me.moreless

    One of the most pivotal and revealing episodes so far in season 4. We see the appearance of Angels, Ruby and Alastair. Sam also reveals what happened to him while Dean was in Hell. Hint hint---cool demon powers. One of the episodes that is making S4 the best of Supernatural.

    Anna is a patient in the psychiatric ward of a hospital. She's there because she is hearing voices in her head. Voices of angels talking, there talking about the Apocalypse, Lillith and the seals. Meanwhile, at a bar, Sam notices Ruby and goes to talk to her, despite Dean's objections. Ruby tell Sam and Dean about how Anna escaped from the hospital and that the demons have orders to kill her. Sam convinces Dean to take the job and Dean wonders why Sam would trust anything Ruby has to say. Sam refuses to say and reminds Dean that he still hasn't revealed anything about his time in Hell.

    During the drive to the hospital, Sam flashes back to when he attempted to summon the crossroads demon and make a deal. At the hospital, they find out that Anna was a completely young woman who out of the blue started to ramble on about demons and such. Sam and Dean find among Anna'a papers references to past seals, the "Raising of the Witnesses" and Samhain.

    The boys want to question Anna's parents but find them dead. They do find a clue to her whereabouts. They find Anna in the church and she says that she knows exactly who they are. She hears the Angels talk about the Winchesters and what their purposes are. Ruby arrives and warns that a powerful demon is on his way. Alastair arrives and Sam tries to use his powers to ward him off but is thrown. Dean attacks Alastair and he asks if Dean remembers him, they were close when Dean was in Hell. Ruby escapes with Anna as Dean recognizes who Alastair is. The boys are forced to retreat.

    Dean insists Ruby can't be trusted. Sam says she can and she saved his so he owes her and explains-----flashback to the summer when Dean was in Hell-----A drunken Sam is attacked in his hotel room by Ruby and another demon. Ruby says Lillith released her from Hell in exchange for killing Sam. Instead, Ruby kills the other demon. They hit the road and Ruby says that now she's on the run from Lillith because she saved Sam and he wants to know if she can get Dean out of the pit. Sam kicks Ruby out of the car and orders her to get another host or he'll send her back himself. Ruby goes back to Sam in a new, dead, body, with proof of the host's death. She tells Sam that he can kill Lillith and she can help him do it. They need to get it right this time, Sam needs to sober up and Ruby will teach him everything she knows. Sam fails the first time he tries to pull a demon out, he's disappointed and Ruby assures him he will get better and that he will get over losing Dean. She tries to console him, Ruby kisses Sam, he resists at first but gives in. Dean of course is disgusted by the very thought of Sam and Ruby together and Sam continues on with his first attempt to kill Lillith-----Ruby warns Sam he's not ready but he insists he needs to do it now. Sam goes to the house where he believes Lillith will be, however, instead of Lillith, there are two other demons. Ruby arrives and joins the fight. She kills one of the demons. Sam forces the second demon out the host body and sends it back to Hell. Sam continues on by saying that Ruby helped him survive without Dean and he would be dead without her.

    Ruby arrives in a temporary body, gives Sam and Dean an address and leaves. The boys meet up with her and Anna. Anna finds out what happened to her parents. Castiel and Uriel arrive and announce that they are there for Anna and she is to die. To be continued...Argh!! Be sure to tune in the next episode.moreless

    This was a very revealing episode about what had happened to Sam during the months we missed. You see Sam and Ruby do it ad I found it really really funny when Dean said "Wow too much information or detial I dont remember" but it was funny, there was some nice little action at the end and the episode was very enjoyable.9 out of 10.moreless

  • More loose ends tied up; Ruby's role in Sam's life since he lost Dean; Dean's uneasy acceptance of this turn of events etc.

    First off, the second part to this story arc gets a higher rating than this one. However, the scenes from this episode which reflect Sam's desperation and pain at losing his brother help us understand his obsession with finding Lilith - whatever it takes & why he is using his demonic powers.

    The actor portraying Alastair was good; he certainly left an impression. Dean's ghosts from hell are coming back to haunt him even more, as if he doesn't have enough nightmares already. As for Ruby - I never did like the OTT know-it-all way in which she was portrayed by Katie Cassidy in Season 3. Yes, she had been a witch before and was now a demon, but neither Sam/Dean had asked for her help in the first place. Genevieve Cortese's version of Ruby is a little over-compensating as a result. She comes across a bit too compassionate for a demon, but as she duly reminds us, she remembers what it feels like to lose someone...so I don't know what kind of demon she is. The story in itself gets more interesting, with an insight into what's hot in the Angel grapevine. Apparently there are some Angels who dislike Sam....and others that don't. Dean's identified as the hope the Angels have in defeating Lucifer. Dean also starts to appreciate what Ruby has done in helping Sam stay alive after losing Dean, but I'm sure he still has doubts about her actual goals. He's only accepting of her since he doesn't want to lose Sam.

    What I have a problem with is the nagging contradiction this episode throws up, especially in how demons locate their targets.. First off, when the brothers find Anna in the church, Ruby comes in and tells them that they have led Alastair to Anna, since he followed them. Secondly, Ruby takes Anna away to a hideout, and informs the brothers where they are, by possessing a maid & handing them a note since there are demons all around the motel. They sneak off, without the car and all. Yet in the flashbacks, after Ruby jumps into the body of a comatose girl whose life support has been discontinued, she magically turns up at whichever hideout Sam was at - how did she find him so easily?

    Point is - if Alastair is a higher grade of demon than Ruby is, why would he need to wait for the guys to lead him to Anna whilst Ruby always seems to easily know where they are?

    The other bugging thing is when Sam tried to make the deal with the Crossroads Demon, he was told that Lilith didn't want his soul, and they were pleased that Dean was in Hell, where they wanted him to be.

    Yet, Lilith gives Ruby the chance to redeem herself if she could find Sam and kill him, which of course she doesn't. Season 3 pointed to the fact that Lilith wanted Sam dead, and we all know what happened when she tried to kill him herself. So what this all means to me is that Lilith can't harm Sam with her powers, but apparently a lesser demon like Ruby would be able to, with a knife. If Lilith could possess little girls and wield her power....why couldn't she possess anybody else and kill Sam herself, say with a knife or a gun or whatever? She must know that Ruby hasn't followed throughshe possessed Ruby's host body once before and sent Ruby into damnationshe sure as hell (no pun intended) could do it again. So does she really want Sam dead or not? I'm confused...

    Maybe she has discovered that she needs Sam to completely unleash his powers ....the final "broken seal" to setting Lucifer free. Maybe that's the redemption that Ruby is earning for Lilith letting her go...set Sam on the path to getting Lucifer free.moreless

    • While Dean and Sam were at the Milton house they have left evidence of them being there like fingerprints on several objects. They both have their fingerprints in the police database, sooner or later the bodies will be found and evidence will point again to Winchester brothers. Edit
    • When Sam starts to tell Dean the story about how Ruby saved his life, he is holding a towel to the cut he just stitched up, and his shirt sleeve is bloody from the wound. When the flashback takes a break, Sam hasn't moved from where he was sitting, but his shirt is spotless and there is no blood on his arm or towel stopping the flow. Edit
    • When Dean and Sam leap out the window, the shot from inside shows the two brothers hitting the window simultaneously. However, when the camera cuts to the outside, Sam emerges first and Dean is considerably behind him. Edit
