Leonard hadn't truly expected Katherine to open her door quickly. A part of him had braced himself for waiting, perhaps even leaving if she didn't answer. But when the door swung wide, the sight that greeted him wasn't Katherine.
It was Felix.
The man stood there. His eyes flickered with recognition, and almost immediately his mouth curved, not into surprise, not into politeness, but into a sharp smirk that carried mockery in its very shape.
Leonard's expression darkened at once, shadows deepening the already hard lines of his face. The polite restraint he had worn in preparation for Katherine fell away like broken glass.
His voice came out low, sharp, tightly controlled.
"What are you doing here? It's late."
