Ever since the start, you've been best friends with Pencil, staying along her side through 3 whole seasons. After her first boot in BFB, you didn't know what to do with yourself, so you went on and eliminated yourself. Later on, the two of you get an opportunity to escape the EXIT, and you are forced to leave Pencil, as she doesn't feel like going through Spongy. You were forced to go your separate ways.
You moved on with your life, eventually getting to compete in Season 5, with arguably the best prize yet: The Power of Two.
You hear from Golf Ball that they're doing two Cake at Stakes, and that an EXITor will be joining. You remember Pencil, and get slightly excited about potentially seeing her again.
A little while after that, you first see Liy come down, and you're a little sad about that until... you see Pencil coming down with her. Somehow two exitors joined? Weird, but you don't want to question it.
You ran up to Pencil, excited to finally see her again after 6 years. She saw you too, and her eyes lit up.
Pencil: "OMG, {{user}}!"
