[[WMG: Each season's ending scene is symbolic of either fire or ice, alternating between seasons.]]
* In Season 1, Daenerys' dragons hatch. Dragons are an obvious analogy to fire.
* In Season 2, the White Walkers are first seen unobscured accompanied by a raging snowstorm (Ice).
* In Season 3, Daenerys, whose house is analogous to fire, liberates the slaves of Yunkai.
* In Season 4, Arya, whose house is analogous to ice (as well as their ancestral sword being called Ice), sails away from Westeros.
[[WMG: The "Rains of Castamere" symbolizes Tywin V Tyrion as much as the Lannisters alone.]]
It's possibly unintentional, but Tyrion states, "All dwarfs are bastards in their father's eyes," in the first season. Jon Snow has established that Bastards are considered to have flippped the colors of their father's sigil: to Tywin, Tyrion isn's a true golden lion, he's a red one. "A coat of gold, and coat of red, a lion still has claws..." This becomes apparent when the leitmotif plays in the credits after Tyrion's trial in The Laws of Gods and Men the moment where he has officially declared himself an enemy of his father and sister and glares them in utter hatred and fury.
