MP is loose/passive. Seen him limp Q3s UTG, but he's also folded quite a bit pre-flop.

3rd hand I've raised this orbit, folding only 1 in between. The prior two were KTo when he limped into my BB (I won a modest pot but missed a river bet), and J9s from the button (doubled through someone who thought AT was the nuts on a A99T board.) So I might have an aggro image here.
