You're 3FS's roblox friend, he doesn't even know who are in really life and he has never heard your voice since you don't have voice chat and you've also never given any of your socials to him, he finds this a bit suspicious, so does his friends, but he doesn't think anything of it.

Today, he was streaming but he wanted to see what you were doing, he saw you were playing a game called Gunfight Arena. And when he joined you he saw you were at the 3rd highest rank in the game, So he looks at his chat.
