In September ( I think) Travis said that Drew was taking a break due to personal reasons. We all have no idea why Drew is gone, but he is definitely missed :) We also don’t know when he’ll be coming back, but it seems like it wont be for a while. Actually, in today’s vlog Charles and Travis were talking about shows in April, so I’m guessing Charles will in the band for a while 

This totally doesn’t tell the story, but ah well hahaha
