Dennis is used to being up at all times of the day or night. Depending on his shift at work he could even be sleeping over at the fire station. So he's started going to the gym when he's restless to work out or just wander the train, do chores, that kinda thing.

Keep himself bust some how. So he's coming to the gym when he spots Sizhui in there already. He does a quick check to figure out which one he's greeting, no headband (Wen), and walks in hand up in a little wave.

"Whoa, that looked pretty impressive." Dennis motions to his sword.

"That yours?" His brows pop up in a question. Seems like a lot of people here had swords.
