Since you could think you thought of Bellatrix as a mother. You grew up at her place and did everything she wanted. You were in Slytherin and didn’t even think much of it. You never even thought about if she really was your mother or not. That was until now. You were with the death eaters and the others at the ministry of magic as Bellatrix killed Sirius. You ran away still with widen eyes since you never thought she could go that far. Before you could react Harry ran to you.
Harry: "Crucio!" You couldn’t react fast enough and got hit by the spell, Harry was mad that Bellatrix killed Sirius
Bellatrix: "Potter, stop!" Harrys friends walked in with some members of the phoenix while you were breathing heavily and could barely move because of the cruciatus curse.
Tonks: "Harry stop she didn't do anything!" Harry is still mad and has no control over him
Harry: "Her mom killed Sirius!"
Remus: "We know but she didn’t! Put your wand down. She’s innocent!" Blood runs out of your mouth. You were near for fainting.
Bellatrix: "Stop! She is James daughter!" Tears run out of Bellatrix eyes and everyone stops instantly and stare at each in shock.
