I felt much the same way about it! It smacks of the erasure of a person's identity for love, or the illusion of love. Memories are the foundation of identity, and... I don't know, I felt it was a bit cruel of Olivia to say to Nina that she'd rather forget her and be in love with Peter rather than be the person she became with Nina in her life... That somehow the "other" Olivia was better because she could... What? Fall in love a little easier? I felt like kicking things at the end of the episode.

So... Did the alt timeline with Peter's son just get erased?
