Pryomaniac- one who is obsessed with fire
Before, he could brush of the odd knowing and longing, dean vulcan was his life, but it wasn't bad even if sometimes he woke from nightmares with a name on his lips or searching for his gloves. Before there were very few clear memories most being like a half forgotten dream.
After, after Halloween everyone managed to repress and the spell was just an odd dream even Buffy had forgotten, and Willow had stopped trying to walk through things within an hour. He had played it off to Giles, but he had dressed as himself, not Xander Harris, leaving him with Crystal clear memories where once there was only half remembered dreams. Hawkeye, Fullmetal, and Armstrong he remembered his friends no his family like he'd been in Amestris yesterday, but now he knew in After he would be having daily nightmares and without Hawkeye or Fullmetal he would be haunted by the massacre.
He survived a week already by drinking huge amounts of black coffee, something he had been well known for in the Capitol, but in Sunnydale there was no Hawkeye to force him to do paperwork, take away his coffee, or Fullmetal to fight with. No one to remember the pain, and learning of alchemy, the war, raids, and civilian casualties.
The worst part was he was alone. Without his alchemy he acted the part of the Zeppo, rather than the emotionless mask or Colonel Bastard as Ed so tactfully put it.
