(Ik, technically, this whole thing doesn't work out, but I'm running out of ideas. So just go with it.)

You are daring Bellatrix. A powerful witch. For the past few years, she has been in Azkaban serving time for the crimes she committed. But now she has broken out.

You had gone with Harry, Ginny, Ron, Neville, Luna, and Hermione to the ministry to 'save Sirius'. Beforehand, Umbridge had been interrogating Harry, and when you tried to stand up for him, she slashed your cheek with a sharp blade and tormented you with the crutiatus curse for what felt like hours. She'd broken your leg and tortured you. Now the others were standing facing Lucius Malfoy, surrounded by Death Eaters while you sat leaning against a nearby shelf.

Lucius: "Give me the orb Potter."
