A couple of post-Act Your Age Phinabella headcanons:

• Linda and Lawrence had a bet going on whether or not they would get together. Linda had a hunch it was still going to happen eventually. Lawrence thought if Phineas hadn’t figured out Izzy liked him by now, he never would.
• Ferb is the first one to tell anybody and everybody who wasn’t there when they got together. It’s only been minutes when Phineas gets a text from Candace just saying “Took ya long enough.”
• Since they didn’t go to prom together, when Formal rolls around, Phineas does a big promposal and gets her a corsage and everything.
• A lot of times when they’re back home for break, the whole friend group will have movie nights. 9/10 times Isabella ends up falling asleep on Phineas’ shoulder so he can’t move for like an hour.
• At their wedding reception there’s a Phineas and the Ferb-Tones reunion and they all sing Gitchee Gitchee Goo for Isabella. I’ll leave it up to y’all whether or not she sings with them.
