There's a narrative choice I call a Hobbit moment—it's any moment of Hobbit bravery in LotR—trying to save Boromir, "I will take the ring to Mordor, though I do not know the way," Pippin singing to Denethor and then being a general badass, Merry stabbing the Witch King, Sam just Samming shit up in the Sammiest way " I can't carry the ring for you, but I can carry you!"—that shit. You know what I mean. It makes me cry. It's when the regular people, the ones who didn't sign up for SHIELD or get bitten by a radioactive spider, or come from a magical other realm. But they fight with heart that's disproportionate to their size, training, muscle, everything. When the scale of everything makes the NY cops the little guys...
And because of all that, there is also the "My friends, you bow to no one." moment.
where the regular guy, the cop when it's all aliens and gods, the mothers faced by a bear.
There's the Millenium Falcon moment, where those guys you'd thought had gone on their way come back and turn the tide of the fight.
And the "I'm getting too old for this shit" where even though it's mostly been the young buck, the grizzled veteran who says he wants to retired knocks the bad guys down good.
I'm looking for a name for the things when the resources you didn't think would get here in time do! And the bad guys get blowed up real good. Beacons of Minas Tirith is kinda it. But not it, precisely. Help coming with Gandalf from the east? We're way too deep in Middle Earth, though.
