Not sure. The potential is definitely there, but he also doesn't strike me as the ambitious type. My impression is that if he'd thought we were on to him he'd have gone to ground rather than confront us.

Additionally, I'm not positive he'll even be looking for her. Long-term use of his telepathy has a deleterious effect on his targets. After a certain point the victim's mind starts to break down under the strain. Jessica had already lasted much, much longer than most of them. It's likely he'll think she's dead.
