One more thought is that his flop bet sizing is odd. Some villains bet so small only with their monster hands to induce calls/raises or feign weakness, some do it as a blocking bet when they want cheap extra cards, some do it as a micro c-bet with air, and some do it with all of the above. So it'd be good to know if you have seen him do that before and compare this with his usual c-bet sizing.

So be aware that when you call this flop, if you hit, you may have been drawing dead or be outdrawn (set, two pairs, flush, (higher) straight).

So I would still call, but be wary if I hit and try to see a cheap showdown.
