They play against other online players. There's another that I recently learned about called Roblox. I never got "into" the multi-player gaming, but from watching others, yes, some games have an area that you can chat back and forth as you move your characters around. Idk that Fortnite does, but, I do think that Sims does on some of their games. Sims seems to be more popular with females, but, there's females who love World of Warcraft, too. Most females, J's age, adore snapchat. The chat disappears after so many seconds, and they can do cute things with their appearance (put on animal ears, halos, etc...). After learning of her move, I think that J was missing a friend, based on her FB. It could be possible that she was making chatroom friends, while maybe chatting with the one she missed. Someone could have pretended to be around her age, and buddied up to her.
