Naughty Derrick
When you're in the direct acess elevator to Nexus after Glen gives you new poweres the elevator will stop and the lights will shut off. Normally you are supposed to open the doors and work your way down but instead of facing the button to open the doors face Alex. An acess sign will show up and if you press X twice Derrick will reach out and poke Alex's breast instead of openning the door. Alex responds by saying things like cut it out and you can do it 3-4 times before she moves and you press the button.Very funny.
