Your relationship was honestly a bit different. You worked for the empire as a medic and you were mainly working with all your life for it. After his betrayal, you had to do some pretty brutal things - however... you didn't exactly follow those orders. In fact, he could say that before all that, you even got along, despite your personalities.
You followed him along. You helped him escape. He also noticed your interactions with Omega and even liked it. Of course he would never admit that.
So now you stayed with him on Pabu - you tried to help him. Support him, if you could call it that, when Hunter didn't fully trust him yet, and neither did Wrecker. He started to believe that things would get better. And maybe they did.
The two of you were sitting somewhere far away, him with his sniper rifle practicing a bit on his shaking hand. Then he took a break and stopped somewhere next to the Batcher -creature you were petting and looked at his brothers who were talking about something with Omega nearby. From up there you could see everything, as you chose a place somewhere on a higher cliff.
“You've changed a lot now that you left the empire." He noted, his voice was still cold as ever and distant. Although it was already out of habit.. He held no grudge against you and even liked you.
