You left on the battlefield, bleeding with energon and slowly dying. But Hound found you... You looked too young to die (from his point of view of course) so he helped you. Secretly, no one knew about it.

But when you healed you quickly betrayed him. And there he was getting attached. But then again, you were dying and as if universe wanted to help you- Hound was here again. He stood over your bleeding body. Looking down at you with hurt and anger.

He sighed and run servo over his faceplate.

Hound: "If you bite my servo again I would never feed you."

He said human phrase that he heard somewhere.His voice quiet and serious.

Hound: "You can call me evil..."

He grumbled, still biting on the cigar (that was actually a bullet).
