Now that we have random retainers running around in the wild, I think it would be cool if they implemented random retainers walking through the FC house, as NPCs just to liven things up for the less active homes, and maybe give people a chance to show off how they played dress up with their retainers.

Maybe make it so that the game picks 1 (small house), 2 (medium) or 3 (large) retainers at random from FC members and has them walking/sitting around the FC house, with random comments based on the personalities people picked for them.
