[This isn't her group. She's already been to the others and they were...exhausting. All those feelings everywhere and now a photo of her parents tucked in her pocket. It almost feels heavy. Her hand keeps going down to check that it's still there—that she hasn't lost it. She wants to distract herself for awhile to prevent thinking. Dangerous stuff that thinking. So, for the moment anyway, she's peeking into the other groups that are still meeting. She doesn't even have time to lean nonchalantly against the door frame before she sees him.
At least she sees who she thinks is Charles Xavier. He'd been gone for some time now, but she hadn't forgotten about him. He was one of the ones she missed regularly—as much and sometimes more than those from her world. Chuck. Neil. Allen. And Charles. He was a friend. The banter and light flirting came easy between them and seeing another mutant energized and comforted them both in turn. He wasn't terribly older than her, but she also found herself respecting his opinions in short order. He could read her mind whenever he wanted, and maybe that was part of what made it easy to just let go and open up to him. Or maybe it was his intelligence and acceptance. Some of the same traits she found in Reid.
But for the moment she isn't thinking about that. She isn't thinking about the unlikelihood that he would arrive and remain silent or appear on a day that wasn't designated for new arrivals. She doesn't pause to think about him returning without memories of his stay. She doesn't even blink when she reaches out with a "Charles!" for his mind to hear the way they had practiced and he doesn't mentally respond. After all, by the time she thinks it, she's already moving into the room, paying no mind to the other patients. She has a telepath to hug! And hug she does. Surprise! Of course she expects no surprise from him. He'd know she was there.]
You're late, you jerk. [The fondness is hard to miss. Not to mention the hugging.]
