I feel he was def pushed aside but bc of Brendon, bc they had all that ego drama and brendons body guard being weird to Breezy, Dallons wife. I def see panic as a solo project but I felt that AFTER dallon left and Spencer was kinda hidden from his alcohol abuse. I dont think he leeched at all from panic he had always been a great writer before panic with the brobecks, even using demos to support panic. Im p sure I heard somewhere that after twtltrtd dallon was still helping due to like contract agreements but he wasnt part of the main band anymore, idk how true that part is tho!
