I see no reason MP2 couldn't have AA, KK, or KQ, so that needs to be in his range as well. Stove says you have 27-32% equity depending on how I tweak reasonable ranges, and you've got better pot odds than that even in MP2 folds, so call.

PS. I was in a very similar hand the other day with KK on a QJT board. I took it down unimproved.
