especially as Abby's not the sort of person to initiate a discussion of feelings when she doesn't have to.

Precisely! We've seen in the past Abby avoids awkward conversations about relationships wherever possible, so if she wasn't interested in him at all, it would make far more sense for her to simply pretend she didn't remember, and let Connor do the same.

The sap in me loves that scene with Connor and Abby on the cliff.

Me too. And even now, I sometimes shout at the screen during the conversation at the end when Connor dithers and Caroline interupts them!
