* BigLippedAlligatorMoment: The snakes buried in the mountain - drinking beer. This made Väinämöinen so angry that he forbade snakes to drink beer for all eternity.

** One more wrinkle about the rhythm: the oral tradition that Lönnrot was drawing from, the last two syllables of each line are sung for about twice as as long as the others. The effect -- which Sibelius preserves in his crowningly awesome ''Kullervo'' -- is quite markedly different from the Longfellow version.
* IronWoobie: Kullervo, whom the rage almost drives into OmnicidalManiac.
* ValuesDissonance: Some might say Joukahainen using his sister to ransom his life with from Väinämöinen makes him rather a DirtyCoward and that Väinämöinen accepting it makes him a StalkerWithACrush.
** Elias Lönnrot probably secretly thought so, too, making it something like DeliberateValuesDissonance.
*** Maybe not just Lönnrot: it's possible that it was meant that way from the start and was the whole point of the story. It is portrayed as quite a nasty situation from [[NamedByTheAdaptation Aino's]] point of view: the cowardly brother selling her out, the mother happily complying in hopes of a powerful son-in-law, and the old and lecherous husband-to-be.
** Yes, but that's okay, because she preserves her virginity and honor by drowning herself.
