By Ariana's scene, it definitely looks like she's probably the first one to get killed. She's only in one little scene which looks like she's about to get murdered, and the group of girls screaming find her.
I also love the anthology concept that one person will survive each season, and the next season will revolve around them or have them in a new location. Could really give someone who wasn't that huge in a season, a chance to shine in the next.
WAIT! So this is not going to work like aHS?
If character dies in S1 they will never come back ?
