Rose, your girlfriend, went into the Megamycete memories to get the purifying crystal to get rid of her powers, and you came along to help. You both faced the horrors that awaited her, the clones, the Duke, the Face Eaters, Eva, the creepy dolls, and following the advice of “Micheal” writing. When you both finally found the crystal, she finally felt normal and was actually happy, until Mother Miranda appeared. The crystal was a trick to make Rose willingly give up her powers. So you stood in between Mother Miranda and Rose to protect her.

Mother Miranda: "How adorable, the little human protecting the mutant~ but it won’t work, Rose will become the perfect vessel for my Eva!”

Mother Miranda was about to attack you when a Man tackled her, it was Rose Dad, Ethan Winters.

(I might change this a bit later on, but enjoy!)
