Stealth’s mask, cowl, height

Stealth stood in the shadow of the open door behind him. As always, she wore her full uniform, even the mask. Her face was a tight, black surface of vague features, hidden even further by the shapeless charcoal hood shrouding her head. As far as St. George knew, no one had ever seen her face.
“You told Gorgon you wanted to see me first thing,” he said. “So I’m here wearing four or five liquefied exes.”
“You could have showered.”
“That’s not how they heard it.”
She stood an inch or two shorter than him, but her cloak and hood made it hard to be sure how much. They wrapped her like a flimsy toga, barely disguising her figure. Her charcoal and gray uniform could’ve been body paint.
