“We’re not brothers! We’re just two sides with the same job! Nothing more. We, are not brothers. Never have been. Never will be.”
Imagine how everyone would react if Remus said this to Roman
(Cuz we know Roman would NEVER say this lol)
Is he saying this seriously? Because if that's the case you know Virgil and Janus would be on high alert. Did something happen between the two of them? Did Remus hit his head or get a brain parasite (which would be common on his side of the Imagination, js)
Roman would be stunned and heart broken, because deep down, he sees Remus as the ultimate pest, a brother.
Patton would be confused, a little sad (mainly because Roman is hurt) and probably a little relieved, whether he admits it or not. His precious little prince never had to ever associate himself with the unsavory duke, no matter how bad that idea is, feelings are feelings and Patton has a lot of them...and biases...
If he's just being a shit for the sake of getting a reaction, and it's not exactly obvious, Virgil would shift his worry to Roman and Janus would watch the chaos unfold with a glass of wine.
If it is obvious, no one actually reacts except Patton. And then he dials back any upset feelings and goes into Disappointed Dad Mode.
On the off chance Remus is coming out as transfem, which I would fully support, the confusion and upset would give way to frustration, and then happy warm fuzzy acceptance. Janus still enjoys the chaos with his wine, because chances are he already knew ages ago. Virgil is having a mini crisis because he's gay, he doesn't like women, but he does like Remus, does that make him bi or something? But he was miserable pretending Thomas was bi for years. So much existential dread....that a certain dark creativity can shatter with a little wink and a smoochie
