Xavier gave Ethan that angry look that caused him to back off till he entered the car. That was good enough for him and he left.
Ethan did more bother whether Xavier had said whatever to him or not, all he wanted was to play the little innocent boy. Well, he hadn't planned on them meeting with Xavier here, and killing him will be a mistarget that can put him in trouble. At least, for what he knows, Oscar wouldn't even find r slightest pleasure in coming to help her at all, and right now, it might just be a misjudgment, something that she can not do without.
