Am I missing something or was there something wrong with the timeline in the last episode?
Nothing big, just a tiny detailed (that I kept thinking about for the rest of the episode :/).
At the beginning, Amy says:
Last time he was like this, he figured out electron transport in graphene.
So that's the episode where Sheldon is in the pool of balls at the end, and when he finds out the answer at the Cheecake factory later.
Then Amy says:
The time before that, he was making a list of who's allowed in his tree fort if fe ever gets one. Still can't believe I didn't make the cut.
But how could she have made the cut?! She didn't even know Sheldon at this time!
The pool of balls episode was S3E14, and Amy appeared in S3E23. So Sheldon was unable to put her in his list, and Amy is not even able to say "Last time he was like this, he figured outelectron transport in graphene." because she wasn't there.
I agree, it's a detail, but it bugged me for the rest of the episode.
So am I missing something or is there really a tiny timeline problem on that scene?
