Todd Alquist Kills Innocent Kid
Taking his drug kingpin up to the next level, Walt gets help from Todd Alquist who worked with him and Jesse at Vamonos Pest. Joining with Walt and Jesse for a heist from the top of a moving train, the three secure the methylamine and instantly Alquist has a place in Walt's heart.
Unbeknownst to them, a child, young Drew Sharp, witnessed the whole occasion. Todd pulls out his pistol, shoots and fatally kills the boy in the chest. As Jesse screams in protest, Walt basically looks like it "one more log on the fire," and we all witness just how low in the dirt Mr. White has become.
