It is still possible of a Birdy + mb team, but I think that's a bit unlikely. Though Birdy dropped the mb wagon at L-1, I think she'd still vote her scumpartner out partly due to old busing habits and partly to remain seemingly neutral
If I think about it, Birdy being opportunistic with her vote by being a part of every wagon makes her more scummy than not
