- Guard: It's not possible, Inspector Lestrade, this door is on a time lock. Nobody could've had access to this room last night.
- Sherlock Holmes: It clearly is possible, or you wouldn't now be in need of our services.
- Dr. John Watson: Subtract what belongs from the scene, and anything that remains becomes suspicous. A page from your own book, and it served me well.
- Sherlock Holmes: Yes. Interesting that you so handily found the evidence amidst such clutter.
- Inspector Beth Lestrade: Hm. He said Roylott's got answers. That's just what I'm in the mood for, right about now.
- Sherlock Holmes: By all means, lets get some.
- Sherlock Holmes: In his own, twisted way, he did it out of love. But at some point, he lost sight of the truth, and then he was lost.
- Dr. John Watson: And what would that truth be, Holmes?
- Sherlock Holmes: The truth, my dear Watson, is that even an eminent herpetologist should not attempt to tip the scales of justice in favor of evil.
- Inspector Beth Lestrade: Scales of justice, Holmes? Ugh. Good grief!
