Hamlet

What episode is 2:21 from in this video?

http://images2.fanpop.com/image/photos/14200000/Haibara-Ai-ai-haibara-14288068-640-480.jpg I saw this screencap and I'm wondering if something went on at this scene, can someone tell me which episode its from?

I wish to know when those instances occurred in the anime and the manga. Sry, for the inconvenience.
