Serena looked at him, then touched the pendent around her neck. "Yami...Duke isn't the only one who has made it out of one of those duels...and kept their soul...I did. I'm not sure if Joey told you but...I wasn't the one who started fighting the Brotherhood...my brother was" She reached into her pocket and pulled out the picture from the apartment and showed it to Yami. "He is best friends with Adam...they were trying to track the attacks and find a pattern..." 

She leaned against the wall by him, fighting back the tears that wanted to fall. "I had gotten back from a tournament in Europe...I didn't even know about all of this...I got a call from a friend of mine when I landed...that there was a huge duelist party downtown...so I went. When I got there...the fighting had already started. Kids running for cover as one of those hooded freaks was dueling...my brother. He was using his deck...cards he had been using since he was a child...I ran to help him but one of the hooded guys monsters took a shot at me and hit me...net thing I know Aaron is holding me in his arms, and this was around my neck" She pointed to the pendent. 

"He took me to Adam and that's where I ran into the Professor...my father. Aaron and I haven't seen him since our mother died years ago...I slugged him in the face...but then they explained what had been happening and that people were getting hurt..." She paused, a few tears running down her cheek. "It was that night Aaron got another call...he went and tried to fight off that freak from a daughter of another professor...Hawkins I think his name is...Aaron lost that duel. His been in a coma ever since...and I took his place. The fighting....the darkness...I just fell into all of this because my brother needed me...now to find out that I have some part in the past...that my own father couldn't bother to tell me what this pendent could do...I just can't..." She lowered her head, tears running freely now. 

"I'm a duelist...and I'm fighting a war to save the world...and I have no idea what I am or what I'm doing..." She covered her face with her hand. 

Yami would of course notice how her brother looked like Mahad.
