NL10, TPGK facing strange shove on the turn

[platty]

Opp seemed pretty aggro and a loose caller, no stats on him, i was around for like 5 hands at the table, he double barreled, then showed a draw in one hand. the blinds were on the tight side, like 10\6 or smth, so didn't expect them to call.

confused about this, i know the best line would have been to bet on the flop and take the pot like 90% of the time, but as played, do we call here or fold?
