I uh, I REALLY apologise if you guys didn't wanna see this LOL. Not every day I draw something like this I know...

I-I AM ABSOLUTE TRASH.

So I have this headcanon that Arthur has a bit of a secret kink...being tied up or restrained in any way kinda drives him wild.
Like this one time, the gang had split up into pairs to go searching for a 'zombie' (which turned out to be Old Man Jenkins), and being a typical villain, he found Lewis and Arthur, and tied them up back-to-back and gagged them to deal with later.
Lewis is trying his best to wriggle free, but he notices that Arthur's back is getting a little sweaty against his...and he's panting really hard, and he can see out of the corner of his eye that his face is all flushed. And...oh god, is that a lump in the front of his pants...? Minutes go by and Arthur has been struggling harder and harder, all of a sudden he kinda throws his head back, resting it on Lewis' shoulder as he...

Well.

Lewis decides not to mention it once they got free, and after his death he had quite happily forgotten about it. That is, until he captured Arthur and pinned him against a wall in his mansion. He couldn't really ignore it then.
