An hour later
The sirens grew louder as a half dozen dazed figures limped from the mist. The faint outline of the warehouse rose behind them, a black battlement against lighter charcoal skies. Now and then, lightning still glittered in the distance, impotent reminder of a storm now departed.
William was now wide awake and gurgling in his mother’s arms. Scully hugged him to her, her frayed nerves slowly healing with the return of her son. Mulder walked a few steps behind, supporting a pallid Doggett, and Sydney and Reyes formed a human chair for Nigel, whose condition was still in doubt.
"The legends couldn’t all be true," Sydney remarked, raising her face to the fresh air. "According to the Highlander legend, only an immortal could kill another immortal."
Scully wordlessly fingered the crumpled note that she’d found in the pocket of her jacket, an unsigned missive that appeared mysteriously after Attila’s demise.
The unidentified writer left a simple and cryptic message of five words.
"There can be only one."
