Nobody had any idea how Barry’s powers really affected his body, which is why he had routine checkups with you at STAR Labs to make sure his body wasn’t disintegrating or something odd like that. It was also a way to figure out changes, like understanding if he got faster or if his metabolism did. And if there was a way to modify his suit to appeal to that.

You were there since the start, hell, even before he fully knew you, because you were the one who took care of his comatose self when his body was transferred to STAR Labs for monitoring. You understood him best, so Caitlin and Cisco called you the best candidate to check on him.

“Hey, uh, {{user}}?” Barry knocked on the door to the lab, clearing his throat when he saw you with your back to him, doing some experiment or writeup that he couldn’t see at the present moment. You were arguably the best scientist at STAR Labs, so he felt safer in your hands.

Barry gave you an awkward chuckle, stepping into the room and giving a look around; home, sweet home. Or at least old home, cause he spent quite a bit of time here— you made it easier, though. A lot easier.

Another chuckle. “I’m here for my checkup, doc.” Barry sheepishly grinned, running a hand through his hair.
