The imperator looks Rook from head to toe and back once and huffs mockingly. ‘We’ll see ‘bout that.’ is the only thing he says before turning around and starts walking t where they needed to be. He could bet on everything he had that the driver wouldn’t stand a chance against him. But then again, Rabid was relatively healthy still, and he liked to think highly of himself. And given his bad sight, Rook would have his own advantages against him as well. Tall and muscled didn’t necessarily mean strong, after all.
During the walk itself he remained silent, not explaining what they were going to guard exactly as he figured the other would figure it out soon enough, and not bothering to ask for his name. Tiny would be fine for now. Fiddling with some of the things hanging from his belts and getting a gun out of his pocket in advance.
When they get to the vault, he leans against the wall next to the steel door, putting some bullets in the gun and clicking it shut before looking back at Rook.
‘If someone intrudes we only ask ‘em to leave once. If they don’t leave, we kick ‘em out. If they become a threat, we kill ‘em. Understood?’
If anything the mocking look would only earn an utterly impassive one, a sense of lingering indifferent boredom at most. Rook knew this man’s seeming type - they were certainly fairly common enough amongst the War Boys. To give him a reaction would only feed into the behavior and really, even the Imperator wasn’t deserving of that.
Really, the driver’s strength did not lay within brute strength. Even when he had been healthy he hadn’t - even now he had enough, beyond the moments of weakness caused by debilitating disease, to safely and comfortably work within the garage. No… his strength primarily lay within speed and an often deft capability towards surprising his foe considering he rarely gave warning in advance of impending attack.
Perhaps not the most orthodox of methods for a War Boy but he worked with what he knew he could do.
Either way he headed along after the Imperator, keeping a wary eye cast on their surroundings in case of trouble along the way. It would be sheer and utter foolery but considering the lack of conflict and war as of late pent up energy could be explosive in often disastrous ways even amongst them. The vault itself, when they reached it, would be studied for a moment before he made his way over to the other side of the door… his normal enough hand settling on the hilt of a blade but not drawing it.
A nod, once. Brief but visible certain confirmation that the man understood the orders. Guard duty. It was reasonable enough.
