$11 6-max AK facing strange 5xpot bet on 10 10 4 rnbw flop

[1outer]

Villain had been playing solid the whole time, he/she doubled up very quicky in 1st level (called AI donkbet with a flopped set of aces to donk's underpair). Don't really understand why he shoved 5times the pot on the flop here. I had showed a willingness to defend pots that I was involved in during this sng, so I figured that he had to have some kind of hand here, I really don't like calling with 2 overs here. I put him on either A-4 or any pocket pair under j's (except 10's). I had been continuation betting a lot of pots, so if he flopped a 10 I feel like he would have checked to either a) c-raise me or b) c-called.

Most likely I smell small-medium pocket pair here.

easy fold on the flop. By the looks of the overbet here, I'm sure there will be plenty of other opportunities to take this donk's chips.
