He was my brother basically, but no, it's not too much. I can't fault someone for existing. This alternate reality thing sure is weird, but I'll deal.
Making friends with his doppelganger sounds like a very Jughead thing to do. I'm glad he had people while he was here. Even if he maybe wasn't my Jughead. Since Sabrina here isn't the one I know. This is all a lot to keep track of.
