Life of the Party

When Lorne gets his sleep removed to prepare for the firm's Halloween party, he doesn't realize the consequences. At the party, everyone is mystically compelled to do what he tells them; Spike is thinking positively, Gunn is "marking his territory", Angel and Eve get a room, and Wesley and Fred are drunk. Things get worse when the sleep-deprived Lorne's empathic subconscious begins manifesting itself as a huge demon.
