"Whatever, it isn't like I was expecting your help anyway," Billy said and then began to heal his wounds. "If you think you can defeat him, go ahead and be my guest. I won't help since you didn't help me. This is your golden chance to obtain his powers and fears me a little less."
Icarus and Lucyna didn't even say anything to convince Billy to help. He was right in being that guarded in front of them now. Also, it would be pretty shameful if they didn't manage to win two against one when Billy made the enemy show all of his cards. The summoner was strong, but now they knew how to face him.
