"What - particularly - made Isabella's affection for Ferb evident?"

Just played through this a few hours ago...the final cutscene features our Phineas and Ferb saying goodbye to the Danvillians of the alternate dimension. Alternate Isabella says goodbye, and her goodbye to Ferb is a passionate one, followed by her remarking something to the effect that she'd like to get to know the Ferb of her dimension a little better, to which our Ferb remarks, "...but that's another story." Since our Isabella has a crush on Phineas, it would only make sense for the alternate Isabella to have a crush on Ferb...since it's, you know, the opposite and all.
