I dont think Faith had any feelings good or bad for her, she was just there in the room! Everyone had to deal with Buffy dying not just her, ok she was her sister but they all loved her like a sister! She is the baby of the group but theres a point where she should have grown up and stopped being such a brat, as for Forever she was a complete idiot in that ep, she was told not to mess with magic but she did, causing Buffy more heartbreak (the scene where she thinks her mums coming back)...and in potential she milked her moment for everything it was worth (running away so everyone would run after her)....Seriously I hate her Ive never hated a character so much lol 😛
No I could see hints of Daith, dancing together at the Bronze, Dawn wading in to save Faith from the cops, Dawn siding with Faith over the Buffy argument. Remember if things had worked out differently Dawn could easily have been Faith's sister.
I think both Buffy and Dawn could be a little whiny at times but face it, they both had a lot to put up with😉
