Having solved her dilema about Cheese, and gathered a bag full of wrapped Cheese for her new friend Skyra, she returned to the Gym, only to find it was devoid of the Cat faunus she had met earlier. Plus, she seemed rather worried that she smelled back, which implied good hygine, so she must have taken a shower after working out, which would have dulled her scent down so Mokuren could not track her by it. It only then occured to her that suddenly leaving without an explanation could be seen as a bad omen, so the Skyra Girl might be feeling rather upset. Still, if that was the case, then Mokuren had to find her, if only to apologise before leaving again. She didn't want to push - as little as she knew, Mokuren was positive that pushing led to problems - but she also didn't want to leave anything on such a low note. But, the only person she, being a nutjob, could think of knowing where Skyra would be was Ozpin. Because he was smart, and knew everything.
So, without further thought, not that there was much thought to begin with, Mokuren set off in the direction of Ozpin's office, not really caring about what obsticles she might find in the way, but determined to get over them. Skyrea was the first one who didn't seem entirely on edge with Mokuren, and she didn't want to ruin that with a misunderstanding. The whole 'having a friend' thing might even be fun, in the long run.
