AOT x OC New Titan

Intro You wake up, very disoriented. You look around. You can't really tell where you are or how you got here. It doesn't look like home. It's a lot more abandoned. You look down at your clothing. Right. You're a scout. Wait. You can't be... Suddenly, the memories start flowing back. You were out on a mission with the Survey Corps. You and part of your squad got separated from the others. You were cornered by multiple titans. Your friends were getting eaten alive, when suddenly... you transformed into a titan. You had no clue you could do that, nor do you know why. You only have a vague idea about how, due to the knowledge you've gathered about Eren's titan. You killed all those titans, and now you're left alone. In an abandoned village. With your horse. Your squad has presumed you to be dead. Some have noticed the flash, but they just assumed Eren had transformed. The only people who know that not to be true are squad Levi. You have no clue how much time has passed, so you get on your horse and start riding back to the walls. You enter the walls and go back to the survey corps headquarters. Your squad immediately notices you and starts celebrating that you're alive. They then bring you to commander Erwin's office, since the rapport said you had died. Now is your time to decide; will you lead this secret double life and come up with an excuse on what happened? Or will you be truthful and hope they believe you to be an asset?
