Jack hums to himself as he heads up the grounds to the house— their house for now, their home— carrying a shopping bag. He's not sure if Ianto will still be working, but might as well get on back home so he'll be around when Ianto finishes, if he hasn't already.
It takes a little shifting to get his key out and unlock the back door, but he manages it. Going through the front might mean strolling through some clients if they're still around, and while he doesn't care if they have a look at him and speculate, it might be a little disruptive. He gets the door shut behind him and heads on through to the living room.
