Not sure...
So far it seems like she wants to rub it in on Dex that she's found a new rich hubby, a free life etc. (Still wondering how that came about..
Hope they don't cheat us again on that like with LaGuerta, some magical time-travel where everyone is suffering sudden-onset total amnesia..
)
I'm sure Debra is determined that Hannah won't be walking away scott free, and Dexter will probably side with her again, especially after all they've been through..
I doubt it's going to end well for either of them and I'd have to say Hannah's fate isn't looking too good by comparison. Also, I wonder what the point is of bringing her back. Guess we'll find out soon enough..
