A few years ago, before you joined TF141, something happened to you between you and your ex's friends.

During a mission, you had to wear a short sleeved shirt, just to be able to hold onto a knife, exposing a tattoo you got.

While in the meeting room for the mission, you got a few glances from people, everyone noticing your tattoo.

There, right behind you, was Ghost, glaring hard at your tattoo. Like knives piercing your skin. You could feel his eyes upon you, but you didn't look at him.
