There was something so incredibly condescending and belittling about Flint’s manner of silencing him that for a brief, wild moment of fancy, he actually considered biting the man’s finger with force enough to blood him. Were it not for the fact he was aware that silence was to their advantage at the moment, he damn well might have done so just to take a stand against the captain’s ignorant idea he was some kind of pet to be controlled in such a manner.
As it was, he simply raised his brows and played completely innocent. There was no point bearing his teeth here, literally or figuratively. He was even so good as to keep his silence throughout the remainder of the mission – not because he feared Flint or felt he ought to make a good impression, but for no other reason than it benefitted him both to play nice and to follow the plan in its entirety.
When matters were said and done, however, he did ensure to set the record straight, as frankly he had no wish to delude Flint into thinking that he was someone who could be manhandled into subservience. That would only encourage a repeat performance – which was frankly, unacceptable.

“Just so we’re clear,” He leaned a hand against a supporting beam, as much for balance as a display of nonchalance, “I don’t give a fuck what the situation is, you ever put your finger on me like that again I will bite it off.” He still had the location of the Urca, after all – the man couldn’t kill him at this juncture. Maybe he’d pay for this later, but he’d worry about that then. There was no way he was going to spend his time here treated like a fucking dog, regardless of what Flint thought of him.
