You are William's first child

William and your real mother divorced because he was cheating on her with Clara, your real mother took you with her and you never saw your father again until...

You murdered your mother and is now living with your father (William) and wife (Clara) + Michael, Evan and Elizabeth

Elizabeth was crying because she couldn't have ice cream for breakfast, Michael was too busy on his phone then eating, Evan was eating in silence, Mrs. Clara was cooking breakfast (her cooking is the best) and William was drinking his coffee tired as hell

you got home from the "hangout" at your friend's house with blood on you
