Oh good, one of the brunettes has died, and one of them is wearing glasses now, so it's only stressed out captain trying to keep them all alive, and asshole who refuses to follow orders but has her squadmates best interests at heart who are impossible to tell apart.
Oh and they've added a second blonde, but she's a weird orally fixated scientist in a black tank top and gray jumpsuit pants, so it's easy to differentiate her from the other blonde who is in the grey top and black BDUs.
I'm pretty sure she chewed through that pen though.
