Zavier felt that he needed to express his gratitude towards Valerie since they might not get a chance to do so later, given the current situation. Another reason that he had stayed with her was that he knew she was actually very weak and would need his protection should the masked mage decide to attack her despite the front that she was putting.
"Thanks for doing this. I know that you don't feel too good."
Valerie hadn't expected him to express it to her like that. She had thought that Zavier would not have liked her much considering the way that she had always treated her.
"It's my responsibility, after all I was the one who chose this mission and brought you all along with me."
Zavier lowered his head and did not respond for a while. He was thinking of some way to tell her that all of this might have been his fault considering the fact that he had several unknown enemies who might have been aiming for him through this trick.
