Xavier patiently sipped his own tea, and made to look out the window himself so he wouldn't just be staring at her, though she's where a large part of his attention remained.

Not all, however, as it was strange. 
Over the years Xavier had come to think, light-heartedly to himself, that his secondary mutation was connecting to young people. So many troubled youths walked through these halls, at peace once they understood what he had for them. Certainly there would be those who, to put it one way, brought more "teenage attitude". Yet he'd been capable of conveying his truths to each.

Though it wasn't how Ryder remained on high alert towards him, and the Mansion, which was affecting him at the moment. He was no fool. He did not expect to win her trust and gift her security easily. He knew it would be a matter of consistency more than anything else. He expected the result to come in no short time at all.

No, what was affecting him was, for the first time, he felt he wasn't sure what to say to this youth.
Not that the words he was speaking weren't coming as easily as they ever did. They were. 

Yet in these silent moments. . .though no pressure was felt to fill them as quiet was a most valuable resource for a mind, he did find himself feeling...awkward? 
And Xavier realized he was speaking to Ryder almost as he would to any other he sought to help. 

He [i]felt[/i], on this tour, in this conversation, towards her almost exactly the same as he felt guiding anyone for the first time within this place. . .He didn't know how to connect with her as a father.

It was as if in the absence of that knowing, he naturally assumed the form in which he felt most like himself: a mentor.

This troubled him.
The most natural thing to him was feeling just the opposite, now. 

As if he'd drawn a familiar picture with inverted colours.

Xavier was taken from this reverie as Ryder made her statement.

He met her stare, but only responded to the next of what she said: "[color=#7393B3]Well in order to do that, you would first have to tell me what that is you were trying to do?"[/color] Xavier's tone was still calm, though the possible threat didn't sit well with him. One of his X-Men, in fact his first and first student, who he'd come to consider a son and who was approaching fatherhood now himself, had been closest to Ryder's mass carnage. As such, Xavier received the threat as though it were somewhat specific, even though he understood it was general.

"[color=#7393B3]You broke out of Umbra only to seem hellbent on its destruction afterward. This leaves me curious as to why you didn't simply destroy it as a means to break out?"[/color]
