There was few scenes there during that arc. When they had the first meeting and he got his head shaved, after the firing range when daph spilled the beans about Hobbs and later when Justin was smoking and gearing up mentally to go confront Hobbs, while Daph was seeking out Brian to ask for his help. But seriously. We couldn't count how many times he was at the loft, coming and go and staying and coming. It definitely seemed like he lived there...and I am sure he essentially was, showering, eating, fucking, sleeping, waking, dressing, borrowing socks...
