I am only guessing that it was a contract issue or the other actress didn't want to do it anymore. BTW Peyton list is slightly younger than the 2 you mentioned.

I understand one of these (or both are) is most likely true, but...

BTW Peyton list is slightly younger than the 2 you mentioned.

...She doesn't look like it to me. Pretty lady though, they all are. I was afraid they were going to age Selina into someone else too after P. Ivy infected her.

Thanks for the reply/info, Taylorfirst .

I don't understand why people post their wishes or guesses instead of taking 5 seconds to Google some FACTS.
