I think Riley is probably the most obvious example because she's the only person you've had an actual proper conversation with about everything that's going on. Everyone else either doesn't know (Darci/Janelle) or is actually on the other side and suspect things about you that you know (Scarlet) but like even the whole Skyler thing is peculiar. She goes missing for a spell, comes back, is sus as fuck about everything and the MC's just like "welp, anyway let's continue on as if nothing has happened and everything from the past few days and the reaction of your mother and everything is just all normal" Like bitch grow a spine and think about it. There's so many red flags there
