Samus is a raging feminist, Bowser is a masochist, Palutena is a liberal. This puts them at odds, A LOT.
Shulk, Little Mac, Pit, and Dark Pit, who are buddies, like to sit back and watch the fireworks. Little Mac says its 'better than PPV WWE' and Dark Pit thinks that 'it's like Tumblr in real life, abridged'.
Put just seems to be worried that because of Palutena raising him with her mindset, he doesn't know everything about Earth he should. Little Mac, living on a version of real world Earth, is contemplating on teaching him about WW2 is. (I'm going to get crucified for that liberal college joke)
