"I do not know of any parent who would handle this situation any differently," he finally said after a long period of silence. The words sounded hollow to him, empty and far more emotionally filled then he cared for them to be especially while speaking with his children. If there was one thing Xavier had always prided himself on it was being able to control his emotions and to always appear calm and collected and more often than not stoic and uninterested which had served him well over the course of his life. He was anything but any of those things right now and it was making it very hard for him to function let alone be rational or be the things that his children needed him to be in that moment.
"Not yet," he said tersely as he took a moment to lean back, his gaze moving critically over her side to make sure he hadn't missed an errant burn and that her skin was completely covered so that it could begin to properly heal. "I have a fairly good idea of what happened and of who was responsible but right now they are merely hunches. It will take time for me to confirm them and to them into more than hunches so for right now will simply have to make due with the unknown and not knowing." And the not knowing was killing him. He hated to think that Cassius' children had been the cause of one of his own dying because if it were true, if this had been them then his friend was going to find himself short a pair of children and Xavier didn't care in the least what it did to their relationship. He was burying a child, no one was going to be save from his anger once it finally unleashed itself.
"Here," he said as he unstoppered another vial and handed it to her. "Drink this. It'll help with the itching in a few hours. You may sit up now. Let me know if anything pulls or feels uncomfortable when you do so."
