Tintin/Tear Jerker

From the comics
"Captain Haddock: You can at least save yourself. You must cut the rope, it's the only answer! Tintin: Never! Either we're both saved, or we die together!"
 * Explorers on the Moon:
 * Tintin in Tibet:
 * There's also the Captain trying to sacrifice himself to save Tintin, along with Tintin's reaction to his plan.

From the animated series

 * In the scene in "Tintin in Tibet" where Haddock tries to sacrifice himself, he mutters bitterly to himself that he's "just getting rid of dead weight" while trying to cut the rope, which makes the scene all the more painful.

From the film
"Haddock: There was a bottle involved-- Tintin: There always is."
 * The look on Haddock's face after Tintin snaps, "I can smell [alcohol] on you!" after Haddock explains that he lost the scroll to the bad guys.
 * Especially since he hadn't actually been drinking. He was tempted, but the smell came from Allan breaking a bottle over his head.
