Actually, I was not a Spuffy ‘shipper but I do appreciate now everything Spike has gone through for Buffy, and Angel has more personality away from her.
As for Emma’s interest, yes, she doesn’t vocalize it but seriously body language says more than dialogue. Take Emma’s eyelashes. Anytime Hook does something surprising or impresses Emma, her eyelashes flutter. It happens every time. I don’t think we’ve seen her do that with anyone else. And the way she leans in her body towards him instead of away, I mean, if the lack of personal space between them bothered Emma, she would say it does and Hook would step back.
But she doesn’t. She likes having him close and I don’t think she minds the attention either.
