Mr. Giles and a few key Sunnydale alum have been tracking down the recently chosen, guiding them, training them, giving them the full X-Men, minus the crappy third act. But this Dana girl, she's an anomaly that no one could have foreseen. Tortured, traumatized, driven insane by Yoda knows who.
Spike? It's you. It's really you! [hugs Spike, sobbing] My therapist thought I was holding onto false hope, but... I knew you'd come back.
