Backlash: Too strong an emotion in an object JJ touches may override his thoughts and senses for a few minutes, making him believe for that brief instance that he is in the situation of the person that left behind the impression.

Quasi-Sight: JJ cannot forget what he sees through his psychometry, and in his line of work, often times the visions are quite brutal. Too many in too short a space of time could rattle JJ’s brains and eventually drive him insane. He wasn’t exactly thinking clearly when he chose his profession.

Human: Aside from being able to read objects, JJ is still only human and therefore perfectly squishable and killable.

Anti-Tech: While JJ's powers are minimal enough that he can use most technology without too big a problem. Although, his psychometric ability lessens the more high-tech the object is.
