[That's a good Vice Commander! Though he seems a little puzzled at the idea of Hijikata not wanting to push things onto him, (it's honestly surreal; he much prefers the instances in which just about everything permitted has been passed to him,) but just the agreement he receives is enough for him to be pleased by it. He offers up a nod to follow.]

It's not any trouble, you know. It's only natural that I would want to be of assistance to you, as your sword.

[Perhaps not currently his master, but his sword nonetheless, as evidenced by the fact that Hijikata still keeps Horikawa with him. For now though, he'll just give Hijikata a gentle reminder as he leaves the room again.]

You should get ready for bed in the meantime, Hijikata-san! I'll make sure that everything is prepared for you when you're done.

[He's pretty sure he remembers bringing chamomile tea over, so he'll do his best to prepare that to help Hijikata sleep.]
