Hey, tea was definitely fine by him! He didn't object as Kotetsu decided on the drinks, merely nodding in agreement. Just staying silent, Barnaby listened in as Rei explained to Kotetsu about the worlds that didn't have dogs. Another alternate universe--Barnaby would be sure to remember that. Later, he would probably inquire who, but it was good enough just knowing this information.

But as Rei fumbled about the apartment, Barnaby just smiled and shook his head. "It's fine." Sure, it was messier than he would have liked, but not everyone lived such a painfully clean and great life as he did. And 'be nice to Rei' came with lying about the cleanliness of her apartment. It was good that he was used to this; these lies were second nature by now. And better to not worry about it than to guilt her into cleaning.

How did one 'make themselves at home' in a stranger's house, though? His pondering on this came to a near-complete halt at the sight of the furry cat roaming from the kitchen and moving to the couch. They were taking that home...?

"Which one is this?" he inquired.

Did they have to, Kotetsu?
