NL25: Middle set, spooky flat call after shortie push

[automat]

I didnt have any reads as PAHUD doesnt seem to work with Pokerstars anymore. Check with the intention of raising middle set, didnt think too much about the shortie push (flush draw?) but I got really suspicious when MP2 just flat called afterwards. Whats your range for MP2s call? Is there any way you can fold this kind of hand at NL25?
