Will is so grateful for his restored memories that he practically skipped his way to the compound for his office hours. It's such a relief not to feel like a stranger in his own skin anymore, to look at people and know who they are, to have everything make sense again. So when Kate shows up in the office door, leaning there like she's daring anybody to try to toss her out (not that he would, unless he had a patient) he grins. "Hey, you," he says warmly. "You can actually come in, you know."
