Is hawthorne heights gonna replace casey or just not have a screamer?

they will not REPLACE him, but they'll probably hire another person

Who knows.

Good question though.

They're going to work with what they've got.. So, at the moment not have a screamer.

Maybe in a couple of years they might replace him, but currently they have no intention of doing so.

And, right now, they're just trying to get over the death of their best friend and bandmate.
