Lois and Clark/Heartwarming

"Martha: It's just I'm not able to have children... but I know that if I were to find a baby, I would be the most grateful woman in the world.
 * The pilot has one where, as Lois is convinced she's going to die, tells Clark her secrets--including that she thinks he's an okay reporter.
 * In "Witness" Lois is being targeted by a murderer after she sees him kill a scientist. For the first half of the episode she puts up a brave front until he tries to kill her in her apartment and finally manages to crack her shell, which has her break down when Clark intervenes. Probably the first Aw, Look -- They Really Do Love Each Other moment of the series.
 * "The Prankster" is stalking Lois, who has her really scared after she sees him kill an associate through the telephone. He later calls her at home, which sends her fleeing to Clark for comfort.
 * In "Whine Whine Whine," Superman is trying to find an attorney after a rescuee sues him for a broken hand. He's sitting on a bench when a little girl walks up and tells him that he looks sad, and asks him if he wants a hug.
 * Clark consoling the Clois, after she's done nothing but cause him trouble. Especially poignant given what happens to her afterward.
 * In "Tempus Fugitive," time travel antics bring Clark and Lois to Smallville shortly before baby Kal-El will arrive. Clark winds up encountering his parents, who have recently learned they aren't able to have children of their own.

Clark: And the world's best mom."


 * "Lois, Superman is what I can do. Clark is who I am."
