History Recap / SmallvilleS03E14Obsession

* UnwittingInstigatorOfDoom: The teacher who makes Clark ride in a different elevator car than the rest of the class due to being annoyed by his light-hearted bickering with Chloe. If she hadn't done that, Alicia would have never found out about Clark's powers (and her own teleportation powers would have let her escape the damaged elevator car without Clark). Not only would that have kept Alicia from ever connecting with Clark enough to go {{Yandere}} over him and nearly kill Lana, but it would have let her stay out of Belle Reve and keep her from being menaced by Dr. [=McBride=] and Tim Westcott after her HeelFaceTurn.

* YouHaveFailedMe: {{Downplayed|Trope}}. In the final scene, Lionel interrogates a bound Adam about failing his mission to spy on Clark and Lana, announces that Adam is no longer part of [=LuthorCorp=]'s research project, withholds Adam's medicine, and leaves Adam behind in the room as Adam pleads for the medicine.

-->'''Lionel''': Why did I send you to Smallville? Hmm? [[TheMole To become the best friend of Lana Lang. To find out everything she knew about Clark Kent.]] Wasn't that it? Instead, you have alienated her completely.
-->'''Dr. Teng''': Mr. Luthor, his medication is ready.
-->'''Lionel''': That won't be necessary, Dr. Teng.
-->'''Dr. Teng''': He needs the serum, or he'll die.
-->'''Adam''': I'm sorry.
-->'''Lionel''': I've already made my decision. This patient is no longer a participant in our research program. (''leaves the room'')
-->'''Adam''': Help me. Please. Help me. No! No. No! Help me! Help me!

When Clark and classmate Alicia Baker are trapped in an elevator, he is forced to use his powers in front of Alicia to save them both, and Alicia reveals her own power to teleport. Romance blossoms between Clark and Alicia...until Alicia becomes possessive of Clark. Lana learns that Adam has been spying on her and Clark.

* AbusiveParents: Ambiguous. We know that Alicia's parents locked her in a lead-lined room in their house when she was a child to prevent her from using her teleportation powers, and that Alicia is now psychotic, but [[UnreliableNarrator Alicia is the only one we hear talking about this]] and it's ambiguous whether she went crazy due to this abuse or whether this was just their attempt to keep an already-crazy Alicia in line.
