* ''Tintin in Tibet'': [[spoiler:The Yeti's grief when Chang leaves.]]
** There's also the Captain trying to [[HeroicSacrifice 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.
