While Edward was playing dumb, he should have had an idea about why Billy was thinking along those lines. For the good or the worse, Kate has good eyes when it comes to people, so she should have realized by now that he was helping Alexander with Lily in that regard. Billy thought that girls would like to meddle in that kind of stuff. Still, while Lily was oblivious about it, she would notice if her friends began to act suspiciously.
"Putting that aside, I also heard about Alexander. While your actions in the dungeon town should have been enough, someone of you choosing to accept Jean's offer was probably for the best," Edward said.
"Alexander had his own goals in mind when he accepted that," Billy said.
"I see… Regardless, what are you going to do until your party is back?" Edward asked.
