Not exactly a headcanon, buuuuuut...

Don't you find it funny that 2p! England, the guy who everyone thinks carries around a swear jar all the time and absolutely hates cussing is shipped with the guys who:

1. Cusses a lot
2. Doesn't care they cuss a lot
3. Will never stop cussing

And 2p! England just... is all happy about it and is all like "Oh dear, would you like a cupcake~? I promise they're not poisoned..."
