That's a Hockey-mask painted like a skull, thanks. With a hood up over him. "I took a slightly different route, but saw which way he went." Coming out of the shadows now, to stand with her in the street. "Which means, if we want to keep following him, then we go this way."

Not even waiting for a yes, just kind of assuming she'd follow him. Not scared and inclined to investigate, plus she knew about the library? Seemed good enough for his purposes as he headed around a corner and twisty-alley, where he'd seen the Plague Doctor head.
