Continuity mistake: During the scene when John and Jane are dancing in the hotel restaurant when they first start to dance the large set of windows are behind them but once they start to move just before he knocks her head into the mirror breaking it they now have the large window still in the shot but now on the left side of them even though they never turned except there is a cut. (01:03:22)
Other mistake: When Jane is driving with John on the roof, she jumps out when John breaks through the window. The car then proceeds to accelerate through the trees and into the air. The road is not downhill and Jane didn't place anything on the gas pedal.
Chosen answer: He's asking how many kills she's made. It's just worded such that there's an edge of innuendo to it.
