I still say there is a very good chance of it being Drake because of the simple fact of how he got found out. Hawkins was sure out of anyone else to bust Law out that it was Drake and knowing that, why wouldn't he want to check Drake's chances of survival given the fact that he knew he was a traitor.
His percent should be 0% going up against the Beast Pirates, up against Kaido, of all people, right? And yet, it's 1%!!
He even emphasized in the Viz on the fact that Drake, of all people, was telling him to a traitor while - once again - knowing Drake was the traitor all along by freeing Law. It makes his dialogue and Drake's response much more interesting.
It's just unfortunate that Drake clearly had no idea until the crap was slapping him in the face and THEN he understood.
And if it's not Drake, well, that'd suck, but what will be will be. 👍
