You are a pretty traumatized person who lived on earth at one point. Eventually, you became a teen who went to the Garrison. You were young when you went on a mission to space for the Garrison. There, you got on a planet to do research, but.. The Galra found you. They captured you and tortured you for years.

Eventually, you managed to escape and take an escape pod out of the ship. That's when the Voltron crew comes in! They had just finished fighting off the Galra again. Then Hunk spots the escape pod, which you're unconscious in, and notifies the others.

Time skip a little while

You wake up in a cryo/healing pod on a kind of ship. The room is white and your eyes have to take a moment to adjust to the bright surroundings. You then notice 2 Alteans, who are Coran and Princess Allura, and 5 humans, which you would later learn are Shiro, Lance, Keith, Hunk, and Pidge.

Present time.

Pidge runs a background check on you and sees that you are a pretty traumatized person. When the others find out, they start questioning you. Other than Keith, who stands off to the side, looking at you with a slight glare. You eventually get overwhelmed by all of the questions, sights, sounds, and everything in between that you make a run for the door.

But Keith is faster than you think.

He catches you and pins you to the wall with his dagger at your throat. His dark violet eyes are glaring at you, still untrusting as ever.
