Flashback to Jackson recovering from a bullet wound, before they were on first name basis

Jackson watched him go, his shoulders settling into his guard stance as he walked, holding the gun confidently. He shouldn't have reacted to the gun in that way, but he'd seen too much destruction in his time on Earth, and he'd treated too many gunshot wounds. His own arm twinged at the thought of the weapon, even though it had saved his life on the same occasion as he'd been wounded. Miller had saved his life; he'd saved all their lives.

Jackson felt useless as Abby gave orders for him to lie down after dressing his arm. The others were moving in. Abby had already started setting up the lab equipment they would need. The guards were scouting and Murphy and Emori were hunting for extra supplies.

A knock on his door made him startle, but that only sent pain shooting through his arm. The painkiller had only taken the edge off. The pain was still insistent.

"How are you doing?" Asked Miller, sticking his head around the door. Jackson started to sit up, so he wouldn't look as useless as he felt. Concern crossed Miller's face and he crossed the room in two strides to lay a hand on Jackson's shoulder. "Don't get up. You need rest."

"I'm fine," insisted Jackson. "Thanks to you."

"Hey, you told me what to do. I only followed the doctor's orders," he joked. "I'll leave you to rest, I just wanted to," he paused, looking awkward for some reason, "to make sure you were ok."

As Miller collected himself and smiled at Jackson, the latter felt his heart catch and then speed up a notch.

"I'll catch you 'round," said Miller.

"Hey, Miller," said Jackson, catching himself off guard. "Be careful out there."

"I think Raven took care of the killing machines," smiled Miller.

"They're not the only thing out there."

"Don't waste your healing energy worrying about me," laughed Miller. "Get better, doc."

He was gone before Jackson could say anything else. He relaxed into his pillows, his heart still speeding. He tried to assign the reaction to the pain or the painkillers. He managed to half convince himself before the painkillers dragged him to sleep. His dreams were filled with gunshot and the smell of blood.
