I went back and re-watched the scene where Aiden and Connor first see each other after all these years. There is absolutely no hesitation or guilty look at all from Aiden when he first sees Connor, and all of his reactions throughout don't show any kind of hiding of a guilty conscience or trickiness. Even after Connor tells Michaela that he and Aiden hooked up, Aiden seems mildly embarrassed but that's about it. The show is very twisty, so anything is possible, but I think we are supposed to believe Aiden when he says that this was a one-time thing when he was 16 and it doesn't say anything about his overall sexuality.
I found the case of the week pretty boring, although it was nice to see David Denman again. It wasn't well-told, but I think we are supposed to believe that Gabriel's turnaround was planned beforehand with her mother so that he could be released and run away with Elena.
I'm finding some of the ongoing characters interesting, but I'm not sure that any of them are likable. Wes is sliding into annoying territory. Someone on the show has to be likable in order for me to keep watching.
