[Regal is indeed curious enough to look inside and see just who is looking after the tea house while Sheena is away on the draft. He's not entirely surprised to find Albert there; when he spots the other man, he'll take a seat at a nearby table (not the same one, out of respect for the privacy of whatever he's doing on that laptop) and lean down to give Kogoro a scratch behind the ears.
He won't interrupt Albert-- instead, he'll wait for the other to finish whatever it is he's doing.]
