Keith was quiet as he, Kolivan, and Shiro exited his red lion in the hangar. Quiet even as they walked to the bridge to discuss future plans they all needed to make to take down Zarkon once and for all. None of that was on Keith's mind, though. All he could think about was how he was so easily defeated in one of the few things he excelled at; combat.

The way they threw him around like he weighed nothing. The way they handled their weapons with such mastery that it not only awed him but pissed him of to a high degree. Just the thought of all this and more made his body quake with an anger he hadn't felt in so long that he didn't notice how he was grinding his teeth to nearly dust, the far-off look in his eyes that glared daggers at nothing, or how his hands dug into his crossed arms that he nearly tore through the flight suit.

Anger seethed through every pore of his body that he didn't realize anybody was talking to him until Shiro stepped into his line of sight and clapped his hands together. The ringing jostling him from his thoughts and to the present conversation. It took a split second that everyone's eyes were on him and they were waiting for a response to a question he didn't even hear.

"I… I'm sorry." He said quickly, adjusting his stance and putting weight on his left hip since his entire right side hurt from his shoulder down. He tried his best to hide it but knew that Shiro himself seemed to think Keith's slightly odd behavior was because of the pain. "What were we talking about?"

"Shiro said you had something to share with us." Pidge offered as they adjusted their glasses a little. Her all-seeing gaze taking notice in how Keith held himself.

"Oh…" Keith muttered, his gaze falling to the floor as his face paled. He had hoped to avoid telling anybody about what he learned at the base before returning, he thought Shiro understood the heaviness of the situation that keeping it a secret would have been best… but he seems to have misunderstood how Shiro felt about it.

With a bite to his bottom lip before lifting his eyes to look at Shiro, who still stood before him with a soft, encouraging smile, he took a deep breath and got it over with.

"I'm part Galra. We found out after the Trial or Knowledge or Death because I was given by my father one of their Marmora Blades and didn't know what it meant until now." And he left the bridge, the last thing he saw being the darkened look on Allura's face. How it showed the betrayal in the tears that threatened to fall from her gemstone-like eyes before he pulled his gaze from her and ran off down the corridor, the door sliding shut as no one dared to follow him.
