Aside from the tw i mentioned before, this one has keith insulting people who self-harm. Be wary.

Keith sat at the dinner table, picked up a fork and began to play with his Altean food.

"What's wrong, Keith?" Allura asked. It's just them two and Coran not on a mission right now.

"Nothing, I just have a lot on my mind." Keith claimed. He continued to pick at his food, not leaving the table but not eating either.

"You haven't eaten since yesterday, Keith! You need to strengthen your bones for-"

"I'm not needed anymore for Voltron so leave me alone!" Keith snapped, and stood from the table, turning to leave.

Keith made his way to his corridor, to his room, to his bed, and he sighed, collapsing onto the mattress and pillow. He knows he needs to eat, he's been running out of energy lately, but he doesn't care. If the team can go on a mission without him, if Voltron is fine without him, he doesn't need to fight, therefore in this castle he is useless. On this team he is useless. Eating their food to keep his useless life alive is... useless.

Deep down, Keith's biggest fear is abandonment. He's "the loner" of the team, but only in hopes someone will look close enough and want to stay. So far, no one has, his entire life. Useless.

Obviously, Keith isn't one of those wimps that cut their woes away. He just isn't fond on taking over resources that could be provided to someone more worthy, or more in need.

Keith doesn't plan on eating until someone forces it down his sore throat. Even then, he'll be careful with who he let's close enough to do so.

Suddenly, his bedroom door opens, but there's no one there. Keith, upon suspicion, eases up off his bed and steps towards the still-open door. He looks out and Lance punches his shoulder. Keith pushes him up against the wall with his knife out of instinct.

"Hey! It was just a prank! Calm down!" Lance starts laughing.

Keith clenches jaw, "Do it again, see what happens."

Before Lance can start mocking Keith, Keith enters his room and this time locks the door. He hears Lance grumble to himself, but tries to ignore the outside world.

This was another thing about Keith. He just needs his space sometimes, to cool off. And being without food has made him angry... hangry...

"Keith, how was your time with Allura?" Shiro asks the next day at dinner. The team is back from their mission, and they've already discussed the next steps... which may or may not be taken with Keith, depending on how successful they are. The more successful, they'll use Keith more... a really necessary team member.

"It was fine." Keith picks at his food.

"Keith, you haven't eaten since the day before yesterday!" Coran complains.

"And your point?" Keith looks at Coran through his bangs.
