KQ at 1/2: stop or stay the course?

Primary villain has been playing a lot of hands, so has a super-wide range to call from the BB. Has been pretty aggressive postflop, but I haven't been at the table long enough to see much in the way of showdowns. Been betting pretty much whenever checked to.

5 Handed 1/2

Time for the king and queen to ride off into the sunset or should we call down and see if this guy is some nut?
