Investigate the noise in the hallway

Moving over to the door of your room, you open it quietly and just a crack so that you can peer through. There you see a rather rich-looking couple just entering a room across from you. His face looks familiar to you, but at the moment, you can't place where you've seen him before. You don't know the woman but, judging from their appearance, it's quite possible they're husband and wife.

The door to their room closes. You're positive if you see the man again, you'll probably remember who he is.
