Sherlock tracks Jane with his eyes, silently preparing to call for Mrs. Hudson in the event of an accident. Experiences a private moment of relief when he doesn't have to. The smell would've been awful.

He scrapes the cold eggs into the trash, on top of the offending food wrapper, places the plate in the sink. Pours a glass of water to bring to Jane -- he may want to rinse his mouth out in a moment -- stands in the doorway and holds it out. If Jane doesn't look up, he'll place it on the floor.
