John looked up from his laptop, his eyes catching on the girl's uncomfortably high-heeled boots. "Hello."

Sherlock looked over, respect in his eyes. "How did you know that?"

Zuzanka smirked. "The same way I know what your favorite food is-I observed."

Zuzanka made her way over to the kitchen. Halfway there, however, she tripped and fell face first onto a partially deconstructed bomb, which then blew up.
