While Sonia, Cedric and Kat were out on a camping trip (Cedric always enjoyed taking the girls on little trips when Sonia was going to help her get used to Kat) Kat accidentally pushed Sonia and made her fall back-first into the campfire! It was extremely traumatic for Sonia since she was only like. 6 when this happened?

She ended up being hospitalized for a while and her back was permanently marred with the big burn scars she has. Cedric wasn't looking when it happened, so Kat insisted that Sonia fell by herself, being a dumb kid. Cedric believed her. :')
