How had Alva heard about Potter's Army again? Oh, Ace. That was it. Ace and her need for revenge. If you asked AJ, she would swear to you that revenge was sometimes the only thing that could or would keep Ace going. But who could blame her, after what had happened to her family. Now, Ace hadn't outright told her about Potter's Army, as that was strictly against the rules. Alva had been walking along the corridor when she seen Ace slip into a room that she had never seen before. Curious, Alva followed and discovered Potter's Army. She had to join. Alva had friends and family that she wanted and needed to protect to.
That day, she found herself itching to practice her hand at some potions, and thus she ended up in the Room of Requirement. Then again, when didn't she want to practice potions? The one that she wanted to practice the most was the Draught of Living Death. And thus the room provided her with the ingredients that she needed, as well as a cauldron and such. She walked in and Stephen, a fellow Gryffindor who she had talked to a few times before, was already there. She decided to leave him alone as he seemed absorbed in his work. She smiled a little. He seemed to be improving since his time here at PA.
She walked to the other side of the room before hearing the door open again. She turned back to look over her shoulder, expecting to see Ace or the like, and instead found herself looking at a man that she had never seen before. "E-excuse me? Who are you?" she asked.
