The Other-Dimension Isabella will probably appear the most. I imagine the regular Isabella won't get as much screentime seeing as she won't go with Phineas, Ferb, and Perry to the alternate dimension, and will probably be a background character of sorts. That being said, it might limit the chance of her and Phineas sharing a kiss. Unless Phineas kisses the Other-Dimension Isabella. (O_O)
