Lili Reinhart herself just debunked the HUGE fan theory that Joaquin would play the role as her long lost brother on Riverdale, but one thing she didn't deny was a romance between Alice and FP Jones.
If that be true, then the chances of Betty and Jughead sharing a sibling is pretty high.
So who the heck could it be?!
Camila Mendes (Veronica) responded to a fan's suggested on Twitter, with "can neither confirm nor deny."
Alright, that's a chicken nugget... but there have been stranger things to happen on the show tbh *cough* incest between Polly and Jason *cough*
Could you imagine Cole's IRL twin coming into the show as Betty's half-brother? Not sure our brains wouldn't be able to cope with that.
What are your suggestions? Do you think it'll be a familiar face we've already seen in season one, somebody completely new, or one of the above (including the chicken nugget)? Let us know!
The cast seem to be voting for the nugget...
