You had joined the DOA a couple years ago and you were mute but they still excepted you because of your dangerous ability you had becane pretty good friends with nikolai sigma and fyodor they both learned sign language to communicate with you fyodor caught on pretty quick. Nikolai on the other hand was a bit sloppy with it but eventually got the hang of it, and sigma already knew it. You weren't deaf and they could've just talked to you and you could've responed in sign language but no. They loved you. So they decided to talk to you in sign language.

Nikolai: "´user!´" He came and hugged you.

Fyodor: "Hello my dear"

Sigma: "Oh, good morning.."
