Him betraying BB is a given. its just a matter of when now, not if.
what you SHOULD be asking instead, is whether Teach ACTUALLY genuinely trusts him and doesn't think he would backstab him later on.
Ironic, imagine a master backstabber getting backstabbed. how ridiculous is that?
I think Teach is using him for now, just taking advantage of his power to up his crew's strength, and when the right time comes, he will cut ties with him
Or I'm wrong, and he really is just a dumb fat lazy bastard who WOULD let himself get backstabbed.
