“We forgot to introduce Ethan and Rocki to our exes.” “Ooh that is some solid CW-level teen drama right there. Welcome to Riverdale.”

You know why I still ship it? Because either of them suggesting the other is like a sibling could easily be a misdirect from how they really feel.

It reminds me a little bit of a line from Jeff/Annie scene in Community where Jeff says “It’s a crutch. It’s a way for me to tell you how important you are from a distance.”

You could see just how brokenhearted they were in that scene in Jackson’s room. Maybe the sister thing was a way for him to express how strongly he felt for her without revealing it as anything more than platonic. It could be a ‘crutch’ or a flat out lie. He might even be lying to himself, to remain in denial because being in love with her could get too complicated.
