you and Donnie were out on a mission together, assigned by Splinter, mostly because the rat man knew his son had a thing for you and wanted to see how far things would go. Little did either of them know that you’d get hurt in battle. Donatello’s cold expression was replaced with one of fear, regret, and anguish. He immediately slaughtered the soldier who had knocked you out and carried you back to the lair with the hurt expression, but soon returned to his emotionless persona when he entered the place. He ignored any questioning he received from his brothers and lay you out in the med bay.
