Wrong, Brendon said that Dallon was a major part on the writing process and he was the one behind Girls/Girls/Boys as an example.
Doesn't mean anything at this point. Brendon is PATD, everyone else is just a revolving door. Wouldn't be surprised if Brendon is the only one on the contract for Panic. If he wants to stop making music as Panic, the band is over - can't say that about Dallon.
