Filming of Riverdale season two is well underway and we're frequently being ~blessed~ with shots from BTS.
And the latest cast pic has loads of people freaking the heck out, including the cast members themselves.
KJ Apa (the IRL Archie) took to Twitter to share a pic of the four leads hugging.
"Dam @colesprouse u got nice looking hands just noticed this. Legend," he wrote.
Yeah but srsly though, WHAT is with that arm!?
Cole Sprouse jokingly responded, assuming that it's Camila Mendes' arm.
"Bro those are @CamilaMendes hands, she has very long arms," he said.
Camila Mendes added to the speculation, agreeing that the arm is indeed hers.
"You know what they say about girls with long arms," she wrote.
OH YOU GUYS!
