I just this thought here. If Phineas and Ferb remember that Perry's a secret agent again,and that he fights the 1st dimension Doofenshmirtz, Doofenshmirtz of the 1st dimension,might found out about Perry's private life, and kidnap Phineas and Ferb in order to defeat his nemesis. It could happen. Or not.
