I'm absolutely about to get SLAPPED with an "Are you ill” but something stood out to me when I was referencing panels for Art Purposes. when Bendy and Boris have the other two tied up, Bendy and Cuphead argue over the map.
Something something "MY INK ON YOUR BROTHERS HANDS." -Bendy. Cuphead, who he's talking too, is too busy rage-baiting. But Mugman makes a weird face, and repeats it-
"his.. ink?" Not a statement. A question. He looks... offput, by the notion. I'd almost describe his second expression as "unsettled." Maybe even Queasy!
Later on, during the balcony scene between Bugs and Mickey, Bugs mentions something about Mickey "Working himself thin on Ink," while he grins to himself, like it's something more than what he's saying on the surface level.
Then again Bugs is a weapons-grade freak so it might just be him. But your (nortsauce) panels all have a lot of attention to detail- everything feels very, very deliberate and foreshadowing in these interactions, so while he's always manic... he's blocked out during this scene. A grinning face, whispering to him from LITERALLY the back (behind) of his mind. As if this REALLY DOES have more meaning than "don't overwork yourself."
My first thought was blood. Like- liquid ink, what makes up a cartoon? Ink! But everyone bleeds RED. Cuphead (obviously), Felix’s Love tap form Mickey, when Boris got Milly-rocked by Mugman, Bendy when he got shot on the leg, etc. So that didn’t work. Then I got curious.
And- after noticing this, I went through the comic, and outside of INK Machine and INKwell, I'm... struggling to find any other mentions of Ink. Ichor is mentioned, sure, but not Ink. (My thoughts on Ichor are an entirely separate ramble) The ONLY two character this is seemingly brought up with, are Bendy and Mickey.
All this irrelevant rambling is to pretty much to ascertain- the Blot is a terminal illness that melts someone's flesh? And Ink makes UP that muscle? The idea that someone's body literally liquefied and stained your gloves would explain how Mugman reacted for sure, and it would be exactly the kind of freako vocabulary Bugs would use. ALSO it would foreshadow Mickey having the Blot in an EXTREMELY cool way.
this is the worst way to ask for world building info. I should've just asked "does ink mean toon meat". I'm sorry.
