Lyall watched as Sandra's cards were crushed under the being's steps. If this thing really believed what it was saying about decks having a duelist's heart and soul poured into them to be created, then it was now even more painfully obvious it had disdain for Sandra. For what reason though? Did it just not like the fact Sandra would have been able to contain it had she not made whatever deal she did with it?
The duelist scooped up most of Sandra's deck that had fallen before him, stacking the cards together before placing them in his pocket. The being continued to ask Lyall questions.
"Personal reasons," Lyall said in response to why he would want Sandra back. "As for you though, if you are the spirit I think you are, then I have a proposition for you as well. Your power can be used to help one of my great monsters recover his strength. If you give up Sandra's body and agree to do what I say, then the process will be painless and you'll still be left intact after it's over with. If not though...."
Ryu cut in, smiling sinisterly at him and at the other people before him. Looks like the Infestation Surge from Moth had done its work, now Ryu was tainted with the Iswarm's dark influence and therefore more susceptible to Lyall's.
"Ah, Ryu. Good to see you brother. I trust the taint has been treating you well. Stand down for a while, we can discuss what I have in mind for you later..."
