Burying himself in work had always been a coping mechanism for Nathan, long before he'd discovered he could fly under his own power and harness the freedom and release piloting a jet had once granted. He'd used the distance flight last night much like Peter had done, much like they had in the past, to work off the worst of what losing Gabriel, Hiro and Angela had done, and then Nathan had come home, to Heidi. Since then, it had been nose to the grindstone in the office that was verging on dangerously disorganized, nearly to the point of needing another intervention by Heidi.

But there were still people here, and he had to remember that, and not just those he'd grown close to from this world and others, but his family too.

Including the daughter knocking at the door.

Pushing his pen away, he stood up and rolled his shoulders, checking the clock to find the afternoon had already gotten away from him. The coffee on his desk had long since gotten cold, which made him appreciate what she was carrying that much more when he opened the door.

"Come on in," he said with a nod inward, pulling the door open the entire way before he rested his hand on her shoulder to guide her inside.
