Best Kristian Alfonso scene IMO is a scene during Zach's death. I haven't been able to find the clip, but I'm sure one of her big fans could find it. It was the scene where Bo & Hope are saying goodbye to Zach and Bo is pulling Hope from Zach and Hope screams "I can't, I can't". One of the most powerful scenes the show has ever done.
IMO, Kristian played NT Hope really well. it was OOC for Hope to be a pill-popping psycho, but that doesn't mean it wasn't acted out well.
the 2 NT Hope-related scenes that were really well done were NT Hope's confession & Hope seeing the tape when she awoke the next morning.
