10/20 bottom set in unraised pot

[EnderW27]

I could expand upon my analysis but I guess I'd need to know what about it makes you sick.

But I'll preemptively expand on what I think you're getting at:
Overall, villian has huge implied odds to hit his 3-4 outer (four if villian thinks it unlikely hero's on a flush draw). With stacks of 2300, calling 60 isn't that big a deal.

But in order to call for the implied odds, villian has to be sure he'll get paid off when he hits. This is a pretty raggy board. How does Villian not know Hero's not just taking a stab at it in position and will dump it quickly to any resistence? Villain bucks the odds, hits his miracle card, bets out, and hero folds it?

After a preflop call and a single bet, what does villain put hero on that will pay off that straight with enough money to make the flop call correct?
