5x06 Beautiful Dreamer
First Aired: Oct. 25, 1998 on CBS
Summary: Tess, posing as a schoolteacher, tries to help a child who wants to become a hit man by telling him the story of Abraham Lincoln and John Wilkes Booth.
Sam: Well, this may not be the most famous building in Washington, D.C. But it might just be the most important.
Sam: A heart can change in an instant. And each heart must be given that chance, but... some hearts, well - sometimes a heart is already dead long before the man dies.
Andrew: What you have done was not ordained by God; what you have done, is murder a human being in cold blood. And yet by the grace of that same God there is still time for you to trade that - shame, for mercy.
- Goof (anachronisms): When Booth and the men in the bar are singing Beautiful Dreamer, they are accompanied by a banjo played in the three finger or "Scruggs" style. This is extremely unlikely, as that style was not popularized until the mid-1940s. It's much more likely it would have been played in a plectrum, or strumming style.
