Lemm was going to leave them to their own devices. Perhaps he'd walk off immediately, disgusted at having to harbour a traveller in his shop. A stranger causing setbacks. Uninvited, no less.

...What he does instead is pause for a long time and then drop into a crouch beside them, beard spilling against the floor.

If there's a thought that this is The Hollow Knight in-person in his shop--

He's sick of that already, much sooner than he thought. Never meet your heroes. Ruins your sense of awe. Really grounds you in an unpleasant way. (Not that they're a hero! Not that they're anything. They're just a statue he's seen, they might as well be nobody. Does that matter right now?)

He's been silent for a while. His mistake.
