What would you do if your lover had his mind erased? And then what would you do if he flew into a murderous rage every time someone touched him? It would kind of mess up a relationship, right?

This is the issue on 'Persons Unknown' (Sat., 8PM ET on NBC).

[Spoiler alert.]

During the latest episode, Joe (Jason Wiles) gets his mind "reprogrammed." Unfortunately, this has some serious side effects. Such as erasing his memory. ... And also making him psychotic whenever he comes in contact with another person.

Sadly, this doesn't work out too well for his blooming love affair with Janet (Daisy Betts). When Janet comes close to him, Joe grabs her and is about to toss her over the edge of a building. Not good. See? We told you that this whole thing could be problematic.
