But Klariza wasn't in interviews that Lisa has been in. The twins weren't with the rest of the cast a couple of months ago in a mag. Lisa was at T4 when Merv and Jack weren't. It doesn't mean she was excluded on purpose, Lisa will probably be in the next and her interview is coming up anyway
They never have all of them together, it sucks but it's the way it is. I doubt they said they wanted the other 5 and not Lisa. Maybe she was filming or didn't want to do it.
Whether Klariza is in the credits or not, she is cast. She was in the promo pics and was in the main end credits of the finale with the others. She's like Abigail and Posh Kenneth, they were cast.
