I think this is what happened:
Family Heller is dining at the table, when the phone rings. Mrs Heller picks up the phone.
Honey, this is for you. It'r Mr Berkeley
Mr. Heller: The Guy who plays the Sheriff in your show.
BH: Oh ok. Hello?
XB: Hi Bruno, listen, if you give me the part of Red John you don't have to pay me anymore. I swear to God.
BH: Who are you again?
XB: It's me. Xander.
XB: The guy who plays the sheriff in the show.
BH: Are you not supposed to be dead?
XB: I know, i know. It's absolutely senseless. But being red john could acctually rekindle my career.
BH: But you can't be red john. I had six other people in mind.
XB: Sure I can ! Everybody could be red john. None of your clues ever made sense. Everyone had a phobia even though you gave me the crappiest one of all. Totally unbelievable. But still.
BH: Ok. But Xander please be realistic. Look at you. No way Loreley would have fallen for you.
XB: She was a slut. Everyone could have banged her, right? Look at how naiv she was.
BH: But there are so many loose ends. You are the one that doesn't fit at all. Patrick Jane would wanna know so many things from red john.
XB: So, don't let him ask me any questions.
BH: Wow. You ARE pretty clever. I will consider it. But what about all the fans?
XB: Bruno, please. This is show business. Who cares about fans? YOU are the Boss. Hahahaha
BH: Hahahaha yeah you are right. Congratulations Xander. Or shall i say RED JOHN ;)
