I think it'll be Wallace. Last time Gus hinted at a signing was for Soward, can't see him making such a big deal out of Peachey.
there is also a posibility it is issac john getting a new contract
I doubt he'd send out a cryptic tweet about that.
its hard to see him sending one about naquima as well but it does appear he is part of it or the only one
Im hearing it could be williams, sucks for us if true but we cant keep em all
