The tale of brothers

Wheeljack was telling a tale to everyone in the main room, Ratchet walked in holding a data pad, but dropped it when he heard what tale Wheeljack was telling...

A story where Ratchet had a brother before the war and they fought together against failed experiments, but unfortunately Ratchet and his brother were separated and Ratchet never saw him again. He tried to keep the past.... the past. He doesn't know if his brother is alive...

His brother is my own OC, everyone else is not mine and don't belong to me, the idea was inspired by a video I had saw.
