Grifting 101 - S6-E9
Continuity mistake: The stacks of money the dean takes out, before getting up, changes in the next shot. One stack is completely on the black edge, then is only partly against it and closer to the other stacks. And the stack on the other end is bigger.

Continuity mistake: When the grifting professor and Jeff are speaking in their office after meeting each other, we see the bottle of alcohol change amounts as the camera moves angles (from Jeff's POV to the teacher's). It is lower when the teacher is all alone, and there's more when it's Jeff's POV. (00:20:14 - 00:20:36)

Continuity mistake: During Professor DeSalvo and Jeff's argument, the amount of scotch in DeSalvo's glass changes a few times between shots. (00:08:40)
Answer: The implication is that Jeff will still be teaching at Greendale after Annie and Abed leave. As for who became vice dean? It's never shown, since it's not really important to the series.
