Layla has a stalker so there's potentially darkness in store on that route. Val's main threat would be the other guy from the athletics meet she was flirting with (I've forgotten his name), if he gets annoyed that she's chosen MC instead. Or alternatively the danger could be Tori because of jealousy over the other guy and possibly MC if he's rejected her advances.
I think Layla suggested the girl by the dumpster wasn't the first victim, if there's a serial attacker on the loose then no LI is safe.
