What about the revelation of Ferb's secret from "Spa Day"?

Ferb reveals his secret to his friends (and Irving) and it basically spooks everyone except for Phineas, who's totally okay with it for some reason (again, "Spa Day"). Even though it's against Phineas's better judgement, he makes a machine to delete the secret from their minds (a la "Tip of the Day"). Everything goes back to normal.

Or... maybe something else. What about the "Paris Panic" that people talk about? I've written up something on my computer along the lines of:

Phineas and Ferb invite Isabella to come to Paris with them. Along the way they meet Irving (who mysteriously knew what flight they were on) and Emily, Ferb's old friend from ~puts on British accent~ 'across the pond'. (Secretly, I'd really like to be Emily =]) While they are there, Doofenshmirtz revives his old Mime-inator ("Picture This") and Phineas, Ferb, Isabella, and Emily all turn into mimes. I dunno.

Either way, I think it would be cool to have Emily show up somewhere. She is (don't eat me) a better shipping match for Ferb than Gretchen (now where did that come from?!) or Vanessa, who is way out of his league and also six years older than him (can you say cah-reep-ay?).
