I’m overanalizyng riarkle like I do with Lucaya, so here’s what I see: Riley drags Farkle, she’s afraid and a lttle annoyed about the “blab” thing he’s wanting to do. So, while she’s angry she stops, and pick his coat first than her own. Like: “I’M REALLY PISSED WITH YOU, DON’T DO THIS, I WILL KILL YOU BUT FIRST LET ME TAKE YOUR COAT CAUSE I DON’T WANT YOU TO FREEZE OUT THERE”
