Rafe's never much gone in for all that fashionably late stuff, but he also doesn't go out of his way to be there at 1900 hours. He arrives about twenty minutes after the fact, dressed what classes for smart for him, wanting to make an effort without going too far. He's comfortable at least and nowadays that's the main thing. He doesn't wear ties anymore, if he can help it.
As he makes his way up to the house (as he'll do when he gets inside) he does a sweep of the area with all of his senses, taking in the scents and sights and sounds of the place. He makes mental notes of little details like the number of entrances and exits, windows included, and just how many different scents there are. He'll remain on that level of high alert all night, without fail, but on the outside he'll appear as relaxed as any other house party guest. He'll also make sure to stick to less crowded and more open areas. That will keep the wolf happy, hopefully, or at the very least less irritable.
