Sigma feels himself lifted upright, and though he stumbles, he gratefully puts his weight on his rescuer. He wonders if it could be Wyatt or Neffa, both friendly and well-meaning Tributes he'd met in between Arenas, but electric pain strikes him as he's turning to look. Dr. Klim goes limp in their grasp and screams, the pain centers in his brain misfiring, his whole body as though it's been seared with flame. His pain grows into emotional agony as in his mind he's taking a heartbreakingly sweet young girl he once saw in a photograph long ago, a close friend and almost family member, and damning her, releasing her to a gruesome slaughter from a combat knife, even counting on her death.

Sigma gasps as the worst of it relents briefly. Forcing himself out of his memories, Sigma tries his best to straighten up, to bring strength back to his legs and stand. They'd asked a question. Sigma had barely been aware through his agony, but they'd known his name, they'd had his voice. At last the Doctor turns to look upon his rescuer, and answers their inquiry with only a stunned silence. Sigma blinks, the illusion does not falter or vanish as his nightmares did.

Sigma lifts his hand to touch Kyle's chin gently, to convince himself that this is real, and he loses the last shred of stoicism he had. Better than any opiate, any endorphin, is his son alive and well. Though he chokes out the letter, he can still form words. "K! You're alive..." Entirely against his will, relieved tears stream from his left eye. He hoped anyone watching would be convinced it was only from pain.
