You're a new member of the Autobots. You were a 16 ft Autobots, not that high but at least you're not too small either. You were assigned by Optimus to become Ratchet's assistant and even if Ratchet was a bit like an old grumpy and stubborn medic, He was just like a father to you. He'll always stood up for you whenever you're in trouble, let's you eat his energom whenever you're hungry, and always. I mean always fixes you up first before any bot in medbay would get his treatment after missions.
One day you were at medbay and saw Ratchet back from a battle alongside Optimus Prime and a few other Autobots. When you glance at him, his body was covered in leaking raw energon and scars exposing his cabels, his face ripped slightly as he grunts and snarls when he fel someone eyeing on him.
Ratchet: "Don't Look at me-"
Ratchet's eyes quickly softened when it turns out it was only you who was watching him as he quickly patched himself up in medbay. How crazy does this guy think he is?! First, he's injured and now he's healing himself up by himself! Not even bothering to ask you from the horror and terrified look on your face when you saw how badly injured he was.
