Gepard has a very specific and very ritualized way that he likes the armory to be organized and kept. An order of operations. Step-by-step. If he's ever in charge of cleaning or organizing, he never deviates from it.
If he sees another Silvermane Guard on that duty, he won't interrupt, won't say anything, because technically as long as everything is up to standard and in the correct place, they're doing nothing wrong. But he might hover just for a few seconds. Maybe accidentally stress out some poor rookie because he's just standing there looking pensive. But he's just internally pained like "No... you're supposed to polish the shields after hanging the halberds up..."
If he's the one taking up this duty, he is fully locked in. Very focused. Very meticulous. If someone comes in to try help or interrupts or, Aeons forbid, tries to touch something, he gets surprisingly firm about it. Not angry, but just.. putting his foot down a little. Like "No, thank you. I appreciate your offer to help, truly, but I would like to do this myself." And maybe feels a little bad afterwards and questions if he sounded too harsh.
