That would be an interesting/believable angle. I could see
her going after Deb on some "returning the favour" shit.

Here's my theory, though: I think former Chief Matthews, having
been such close friends with Dexter's father, might have actually
known something about Dexter's dark passenger this entire time.
Perhaps Harry consulted with him about it as Dex was growning
up. He may just reveal this to Dexter and let him know that
Laguerta is catching his scent. I think when Dex finds out about
this and he tells Hannah, Laguerta may be the one whose life is
in jeopardy. Dex won't want to do it, so I think Hannah may take
this kill on behind his back. Also adding to this angle, Matthews
desperately wants his job as Chief back. Once he helps Laguerta
and she helps him get reinstated in the police force (as per
their working agreement), he may turn a blind eye to anything
that happens to her since she's occupying his old position.
