The first time Aftermath steps into the infirmary, it's to try and arrange for some personal medical supplies from the personnel there. He's known that Megatron had been going in a few hours every day for some treatment regarding his long-term exposure to poor quality energon.

He hadn't really been expecting the sight of Sentinel bloody Prime laid out on the berth there though. That gave him a bit of a spark flicker, that did.

Spotting Megatron on the other berth, the old truck warily makes his way over, giving Sentinel a proper amount of space. Better safe than sorry.

"Megatron." There's possibly some unnerved tones to his voice. "Sorry to interrupt your writing, but am I actually hallucinating or is that Sentinel Prime over there?"
