ABC (ended 2006)
Season 4's "Welcome to Liberty Villiage", no doubt about it. That was the perfect episode for me. Syd + Vaughn pretending to be married, some awkward moments--"We're not cold"--, some cute backstory when we find out that Vaughn would have proposed when they were suppossed to go to Santa Barbra at the end of season 2, some steamy shower scenes, amazing lines, and a nice, happy, fluffy S/V ending. It was perfect.
I also loved the second-to-last episode of Season 4, because of the classic "Are we on coms?" moment. And of course the proposal. I have that memorized
I've seen so far only the first 2 seasons and my favourite episode so far is s2ep22"The Telling".One of the most realistic fight scenes between Syd and Allison and the best cliffhanger I've ever seen.
My favorite episode is "Phase One". Love everything about it. The whole scene at the airplain is so awesom, Vaughn revealing his feelings for Sydney, Syd saving Jack from that creepy guy, SD-6's down, and of course, Syd & Vaughn's first kiss.
I never watched any episodes of Alias until season five. I watched I see dead people, and fell in love with the show. So with four episodes left I went back and bought all the seasons that were available and went on a crash course watching them all. So I guess this is one of my favorite episodes because it got me watching one of my all time favorite shows.
I also really enjoyed Search and Rescue from season four. The are we on coms thing was hilarious! I was cracking up the rest of the episode. Priceless!
