Gentlemen...i think we got something here with the vampire concept...
The higher your Danger Room stats, the easier for you. You can see through Jean's deception, catch Laura in the corner of your eye, find Rogue's ass sticking out of her hiding spot.
The better their friendship, the more they work together to help each other. Distracting you from Jean with Rogue's ass, leaving you open for Laura to close the gap and strike.
The better their mood, the naughtier their art when you find them. The worst, the more horror-esc when they catch you.
