Seems like a routine fold to me. It's very possible you're ahead of MP3, though I highly doubt you're ahead of the entire field. I use to play frequently at pacific, and constantly saw players calling down with top pair hands.

In my opinion, raising is the only other option. Though, I think they're a few critical factors that make this fold, rather than a raise:

1. Size of the field/likelihood you're behind.

2. You have no way to isolate villain's weird donk bet, due to the draw heavy board.

3. Anyone holding a pair of Qs is rarely folding, even when it's 2 back (this is particularly true on Pacific 2/4 tables).
