TRIVIA: Wyatt speaks his first full sentences in this episode.
Phoebe was wrong when she brought Cupid to the college campus and said that that was where she first met Cole.

The college campus scene was just Cole seeing if Phoebe knew more than she let on so Cole would have a better case in court against the man that tried to kill Det. Morris.

Christy: I don't have any stuff.
Piper: Well, you will have stuff, every girl has stuff, we have tons of stuff, you can have some of our stuff, you gotta wear somethin'.
Coop: You can't keep running from love...
Phoebe: I'm not running, I'm walking.
Ryan: Let's get out of here.
Piper: Wait, you can't go anywhere. You can barely walk.
Ryan: Look, if we don't keep moving, we're dead. Leo was the only one who knew how to stop them and he's not here.
Piper: Okay well, what am I? Chop liver? Listen, Leo is my husband and if he sent you here for help, then help is what you're gonna get.
Paige: I guess I better go. Don't wanna lose my honeymoon. You sure you're gonna be okay without me?
Piper: Well, we won't know until you're gone. (Paige gives her a look) I'm kidding!
Wyatt (to Piper, who was questioning whether Leo would allow the students to go ahead with their plan): Let them try. Daddy would.
Candor (to Christy, as she sticks her arm through him, slowly killing him): Congratulations... you just passed...the final...test.
