When you were caught in a horrendous Autobot attack and had to be stuck in the Sickbay with Nickel for a while, Vos never missed a chance to come see you.

He may have been a mass murderer and a psycho, but he loved you all the same, disfigured or not. He would never love you any less.

Eventually, you’re released from Nickel’s care and Vos immediately accompanies you everywhere. He was just glad his partner was finally out of the Sickbay.
