(edit) Amy's shrine for Lex features an article about the bank robbery from "X-Ray". (edit) Guest Azura Skye played Michael Rosenbaum's twin sister on the show "Zoe, Duncan, Jack, and Jane" and has a crush on him in this episode. (edit) Aside from being eye candy for female fans in the locker scene, Pete Ross is absent from this episode. (edit) The WB series Buffy The Vampire Slayer did a story like this about an invisible villain. The locker room scene was almost the same as the one on Buffy. (edit)

(looking at the sunset)
Lana: What do you think?
Clark: (looking at Lana) I think it's the most beautiful thing I've ever seen. (edit) Lionel: Lex, you have disappointed me.
Lex: Hi, Dad. Nice to see you too. (edit) Clark: I don't see it.
Lex: What are you, part bloodhound?
Clark: I live on a farm. I'm good at seeing needles in haystacks. (edit) Lex: (to Lionel) LuthorCorp is your company. I'm just one of its expendable employees. As you made abundantly clear when you exiled me to this charming cow-town. (edit) Lionel: Empires are not brought down by outside forces - they are destroyed by weaknesses from within. (edit)

At the end of the episode when Clark is watching Lana and Whitney on her porch, they switch the shot to one from in front of the telescope where we can see a reflection of Lana and Whitney in the lens of the telescope. Unless they were sitting 3 feet from the telescope, their reflection would not appear in the lens, and definitely not when her house is a mile away. (edit) Somehow between when Victoria steps into her bath (with her hair completely dry) and the time she sits down and lies back, her hair gets wet. (edit) On several occasions, Clark doesn't feel the effects of the kryptonite that the invisible attacker has covered himself with. This includes when Troy attacks him, when the door is slamming and the invisible man brushes past Lex, Clark, and Victoria, when Chloe has the dust on her hands. (edit) In the credits for later episodes, a clip of Lex and Clark from this episode is played. However, in this episode, Lex is on the right, with Clark standing behind him as they both go to investigate the mysterious happenings going on in Victoria's room. The scene is right before they open the door and a close shot of Lex and Clark as they approach it. In the credits of later episodes, the same clip is a mirror image, with Lex on the left and Clark behind him. This often happens in TV and I've heard it has something to do with transposing the clip from film to be edited.... (edit) So, Clark invites Lana to see the sunset "tomorrow". Night passes, its a new day, Clark goes to school, sees the medicine. Its night, Clark goes to Lex, talks about the medicine, and Victoria almost gets killed. Now, it's day again and Clark goes back to school! Clark talks to Whitney about the medicine, Clark talks to Lex again, and then sees the sunset. So Clark and Lana didn't watch the sunset "tomorrow" but rather "the day after tomorrow." (edit)
