Isabella's not going with them to the 2nd dimension, so that would have to be between Phin and Alt. Izzy or Alt. Izzy and Alt. Ferb. And if the Dimension of Doom game is anything to go by, Alt. Izzy may actually have a crush on Ferb... Which I wouldn't find surprising, since Ferb is the personification of awesomeness. :P
