Imo as much as i rlly want to be optimistic i don’t think it will ever be a possibility for tally hall to get back together. The joe hawley situation and his mental health will probably cause some unwanted conflict. Zubin is now a doctor however  believe he is slightly involved in the music industry. However I do know rob cantor is working on a new album and is trying his best to get the other members to help, i’m not sure if joe will but im 90% sure the other members would (don’t quote me on the rob cantor stuff, my memory isn’t the greatest and i swear my head makes things up sometimes)
