Greg had his chat with Ianto, he had his kicks around the hospital and when he went to find if Wilson had really gone home and found he had, that amused him as well. It was amusing that a grown man was going to try and sulk at him. Also annoying, when he thought about it, but Greg wasn't going to.
He arrived at the house with a smirk and a whistle, unlocking the door with Wilson's set of keys just to be smug. Coming in and seeing the man asleep on the couch, Greg was careful to be loud as he threw the keys in the little dish the man had introduced at some point to the place and kicked off his shoes before heading in, "Hey honey, did you miss me?"
