Honestly, it's pretty amazing what Root has been to do with the petbot thus far. Matt's confusion and wariness disappears when Lydia greets him. He relaxes and a smile curves his lips as he leans his cane against the wall near the door and takes his glasses off to put them on a small table.

"I feel like I ought to ask how you got the jumpsuit and if it's safe, but I'm a little preoccupied by the idea of you not wearing the jumpsuit," he admits with a wicked little grin. His hands stray up over her back and her shoulders as if examining the jumpsuit for himself.
