Heinz: I actually don't like you. And you can tell because I do actually keep trying to harm you.
Perry: This hatred is mutual! DID YOU JUST CHEAT ON ME WITH A PANDA BEAR? Ok i lied i wanna kiss you really bad actually. Believe me, I am equally mortified by the strength of this revelation.
Season 2: (This is a very good season for Backyard Gang fans)
Heinz: You comfort me and we're kind of friends. We shouldn't be though. I wanna keep being evil so that means YOU have to be evil. So I am going to keep trying to mind control you.
Perry: I kind of want to invite you for dates outside of clock out hours. Work in progress.
Season 3: (The Acid Trip Season) or (The Season of Experimental AUs)
Heinz: Ok I REALLY like you and at this point i kind of want to become evil just to make you proud. My affection for you is unfortunately bleeding into sheer anxiety of losing the one good relationship I'd ever built.
Perry: I am, quite literally, in love with you. Yes, with a mind boggling intensity. I can prove it by showing you an entire album worth of memories in my wallet. If you keep going to Seattle behind my back to see your ex im going to kill you.

Season 4: (Season of Perry. ) (Theyre very married this season)
Heinz: Ok, yes, fine. I love you. Thats fine though, I'm pretty sure you love me too.
Perry: I'm so taken its not even funny. Everyone stop flirting with me. And I need my boss to STOP SENDING ME TO THESE FUCKASS FARAWAY MISSIONS. GOD. Seeing Heinz at them always makes me feel better though.
Milo Murphy's Law, season 2:-
Heinz: Perry? His ass is WHIPPED for me.
Perry: Yeah my ass is whipped for him.
Phineas and Ferb, Season 5: (Weirdly Major Monogram and Bujeet centric season. Which is a choice. Francis is making his divorce everyones problem)
Heinz: I still love Perry but ummmmmm hes pissed at me. Im sheepish about it.
Perry: I'm so pissed at him. I'll prove it by flirting with people and giving them my number. Yes, I know he doesnt buy it for a second shut up.
Perryshmirtz is actively married. Like actually
Sleeping with each other. Non comittal. Arguably the healthiest Perry variant out there.
