Chiron Forgets Jack's Appearance

“The Assassin of Black is not beyond the abilities of the three Servants present here. I myself had once…”

Unusually, Chiron trailed off mid-sentence. The others appeared bemused as they turned their attention to him.

“What is it, Archer?”

“Master, I believe you had sighted the Assassin of Black, as well. Can you see their parameters?”

“Oh, um…”

Fiore closed her eyes as to recall, but quickly opened them to give Chiron a look of confusion.

“I’m sorry, I don’t know. Strange… I’m sure that I’d read Assassin’s parameters… but, why…?”

Fiore put a hand over her mouth in shock.

“That is not all, Master. Although both of us had observed the Assassin of Black, neither of us are able to remember their face.”

“Could it be… some kind of innate Skill, or a Noble Phantasm?”

“It is likely. As the Saber of Red wore her helm to keep her name a secret, so perhaps does the Assassin of Black possess some means of hiding one’s true form.”
