Regina breaking the mirror in the promo may be an indicator of what’s to come for poor Sidney.
I thought that too!
I think Sidney is definitely the most expendable. Part of me feels like it will be kinda “been there, done that”-ish if they kill August, particularly if another character were to kill him, but even if he did die in other circumstances, just because his character did feel like a replacement for Graham in some ways. It could end up turning into “I wonder which handsome dark-haired man with a stubbly beard with a penchant for high-collared black jackets they’ll kill next?”
LOST writers aren’t known for caring how attached the audience is to a character. Although I did read today in the interview with Eion Bailey, who plays August, that they have some ideas for his character next season… but who knows.
Raphael Sbarge, who plays Archie, says they “keep their bags packed” not knowing from week to week if something witll happen to them.
