When Anna is leaving, Lucas says to her "I have a record of women leaving in the middle of the night" possibly being a reference to Cinderella, the movie that Chad Michael Murray stars in.
When the two teams are split up, Felix says to Peyton, Haley and Brooke, "Well, hate to break up Charlie's Angels..." The reason he said this is because Charlie's Angels was a tight threesome just like Peyton, Haley, and Brooke are.
