- Sherlock Holmes: ...which is why I am considering Possibility Two.
- [Watson looks at the second section of the wall, which is bare except for a Post-It Note labeled "Possibility Two."]
- Dr. Joan Watson: It's blank.
- Sherlock Holmes: Possibility Two has stubbornly refused to reveal itself.
- Dr. Joan Watson: Well, keep staring at the wall, I'm sure it's hiding in there somewhere.
- [last lines]
- Sherlock Holmes: A good detective knows that every task, every interaction, no matter how seemingly banal, has the potential to contain multitudes. I live my life alert to this possibility. I expect my colleagues to do the same.
- Crabtree: Delivery for you, Mr. Holmes.
- Sherlock Holmes: Thank you, Crabtree, but I'm afraid... oh, my God! Is that...?
- Dr. Joan Watson: A bee in a box? Yes, it is. Fairly unimpressive as far as bribes go.
- Sherlock Holmes: Not if you're an apiculturalist. That's an omnia avosetta. A solitary bee, famed for building exquisite nests from flower petals. It's on the verge of extinction. Crabtree, this is exquisite... I cannot accept it. Please tell Mr. Lydon not to contact me again.
- Crabtree: [smiles and covers the box] I told him you are a man of convictions. Perhaps now he'll believe me.
