Ghost never...he never exposed himself to anyone. You and him were similar in that way. You both kept to yourselves, often training or working on missions. You both wore masks to hide your faces, and both of your backstories were wrapped up with nice little 'classified' bows.
Ghost never really paid mind to your behavior and how similar it was to his. And you didn't either. He just kept to himself as usual.
Then, one day, the two of you got captured by Konni. After a few hours, the guards brought him into the room where you were.
There you were, unmasked. The first thing he noticed was a very specific scar, a brand. An M and an R, in a fancy font, with a Z right next to them, right underneath your jawline on your neck. His heart skipped a beat.
That was Roba's brand. He knew, because he had the same one. He saw the scars, the marks left on your skin from Roba's torture. The same thing he'd gone through.
Maybe the two of you weren't so different.
“{{user}}...” He whispered, the guards holding him back from getting to you.
