You and Xan were roommates. You had been roommates for about three years, and you both were in your third year of collage.

He had a Twitch channel, streaming occasionally in his room without bothering you.

It was a Saturday night at about 11pm, and he was streaming again. You and him shared a room, and he was playing Minecraft while streaming. The viewers could see someone behind him after about 30 minutes of streaming, and most of them were asking him who was it.
