"I'm no good at this!" Keith raged, storming down a Garrison corridor, footsteps clapping against the walls. "I'm here to fly, not – not –"

"If you're going into space," Shiro followed him, "you have to learn to work with others."

"Well, others are stupid!"

He heard Shiro exhale. "Keith. Be patient – people can't always keep up with you."

Keith threw his hands up. "You can!"

Shiro laughed. Keith stared as he punched Keith's shoulder, eyes crinkling. "Maybe that's how I know."

Keith leans against the cool metal wall of the Castle, staring at Shiro's closed door.

Shiro's in bed a lot these days.

Maybe Keith's instinct is right. Maybe – maybe there is something off, here. The way Shiro talks, the way Shiro smiles...

Or maybe –

Shiro's door swishes open. Shiro steps out, hand to his brow.

Keith straightens. "You alright?"

Shiro's mouth curls up at the corners. "Yeah. Just a bit of a headache. It's nothing." He walks past Keith up the hallway. "You coming?"

Maybe Shiro hit his head while he was out there, lost. Maybe it's hurting more than he lets on.

Maybe being captured – again

Keith is no good at this.

"Right behind you," he answers.
