Season 1, Episode 21:

Salvation
Sam, Dean and John make plans to kill Yellow Eyes and track his movements to a town in Iowa, where they think he will target another family. Sam has a premonition that allows him to figure out which family, but as this is happening, Meg returns and starts attacking the Winchesters' friends and allies and demanding that they turn over the Colt. John tries to trade a fake gun, but is discovered and captured. Yellow Eyes goes after the family that Sam saw in his premonition and attempts to feed his own blood to a newborn baby. Sam and Dean are able to stop him and save the family, but aren't able to kill him.
