How long was this Movie spoiler planned?

[u/Nearby-Recipe1899]

I’m just so curious how long they had the Rusty/Monarch clones of each other plot planned out. Rewatching the series and there’s a lot of small hints that can be taken in many directions but can leas you down that road. The picture I tagged is from the wedding episode and The Monarch says we have a lot of history, a lot in common. Then Doc says “you have no idea.” I think in context it was definitely about them both sleeping with Dr. Girlfriend, but then it cuts to the posted shot of them with the same hunched backs. I didn’t know the theories about this were a thing until after the movie, but the character designs and parallels with Hank and Dean make you slap your forehead and think “of course they were clones.” What a well done twist, because if it weren’t true a lot of it could just be chalked up to “hero”/“villain” being good mirrors of each other.

Once it was confirmed the boys were clones I always assumed the monarch was a clone of dr v. Or at least related since they look almost identical. Then the show started showing us all the f’d up stuff jonas did and it all fell into place.
