Joseph would appreciate the burning of incense, even if he never had before. Anything to clear out the faint, metallic odor that only reminded him of the worst times in his life.

"Ooh, a tour!" Means he could carry the catnip with him in a pocket, because he'd be clothed...probably. Considering the place he wanted to plant it was right under Dio's pillow, this would be a task. He could ask Masaki to do it, but, well, she might not be hip on his pranks, and he didn't want to look bad in front of her. Even though the prank itself was his most innocent yet!! "Sure, I could stand to know my way around."

Sounded like Dio missed his company, and it hasn't even been that long since this whole god ordeal began. Joseph would have laughed, if he himself weren't in a similar, lonesome boat. "A chat to catch up, hm?"

He may have been the guest, but he got the door anyway, giving the other two entry and planning to follow after.
