Jake Abel: Luke
Annabeth Chase : [bringing Percy and Grover to Luke's quarters] Luke?
Luke : [playing Call of Duty on a big flat-screen monitor] Hmm? Hey, guys. Percy. I figured you'd stop by sooner or later. Everybody does... to get away from all that Renaissance Fair stuff out there, you know?
[Luke turns off the video game, stands, and gestures at all his electronics in the quarters]
Luke : But, uh... welcome to the modern world.
Luke : Percy Jackson! Well, you're weren't supposed to make it out alive. I can't let you that bolt to Olympus. I'm the lightning thief.
Percy Jackson : You hid the bolt in my shield. Why?
Luke : Well, when you said you were going to the Underworld, it hit me. That is the perfect opportunity to get the bolt to Hades.
Percy Jackson : Why would you do that?
Luke : To bring Olympus crumbling down.
