I've got a really funny idea for the fanfic! Svetlana is a youtube gamer, and she shouts a lot, as well! So when she loses a game, she screams "OH MY GOD, OH GOD, AHHHH!!!" and when she wins she screams "OH GOD, YES!!! YES!!! OH YES, THAT'S IT!!!" and when she gets jumpscared she screams "IVAN!!! IVAN!!! OH GOD, OH GOD!!! IVAN!!!" (Because when she's in danger/scared, she calls for Russia to help).
Imagine if she was playing Slenderman.
