When Edward realized that he's in fact homosexual and fall in loves with Seth.
EDWARD: OK, Lamb. Are you ready for the surprise?
BELLA: Mmm-hmm!
EDWARD: We're going to Spain!
BELLA: Oh my! That's amazing!
EDWARD: It's going to be so much fun. I rented an entire village for us. Seth is there already, getting things ready. It has a pool and—
BELLA: Hold on. Seth is there?
EDWARD: Yeah. I invited Seth. We talked about this.
BELLA: No we didn't.
EDWARD: Sure we did. You were sleeping, and as I watched you snooze, I whispered, "Can Seth come with us on our honeymoon?" And you said, "Snort grublub." Which I took as a yes.
BELLA: Why would you invite Seth on our honeymoon?
EDWARD: Heh. Better question: Why wouldn't I invite Seth. The dude is amazing.
BELLA: But…
EDWARD: He's so strong and funny. And last night while you were sleeping, we went clubbing. He's a hell of a dancer.
BELLA: You went clubbing with Seth.
EDWARD: Well, not just with Seth. Marcus was there too. It was just for fun, you know. Guy stuff.
BELLA: Marcus?
EDWARD: Yeah, he kept looking at Seth and me and saying, "You two were made for each other." Marcus is such a kidder. By the way, did you know that George Clooney is in love with his girlfriend?
BELLA: But you hate werewolves.
EDWARD: Calling Seth a werewolf is like calling a butterfly a bug.
BELLA: I should have married Jacob.
EDWARD: Good news, Seth and I wear the same size undershirt! Isn't that crazy?
