(NL50) KQo, TPGK battle of the blinds

[Benholio]

I was really lost on this hand. My hand is decent, but I can't tell if Villain really has a hand, or is just playing back at a perceived steal. The scare card complicates things, and I'm not sure if I should keep calling here. Whats your line?

Hero is SB. Hero and Villain both have ~$50. 10-max table.
