A hero who smiles on principle, to spite a dictator who thinks he can control happiness (paraphrasing, sounds better in the text)

Knowing that someone didn't really betray you in the end

"I wonder how Preservation felt when his creations repeatedly failed him"

"Maybe Preservation knew that the emperor of mankind was about to lay down in the ash, never to get up"

"There's always another secret"

"I'm not sure if dismemberment is fatal for his kind"

The big bad evil guy no-selling a couple of spears sticking through his torso

Launching yourself through the air to gank an enemy commander

A bad guy who's nostalgic and trying to do his best for the world just in a fucked up way

Powers of two are a sign of divine intervention

"I write these words in steel, because nothing else can be trusted"

If two people both use the magic that lets them see a few seconds into the future during a fight, they both see a confusing mess of possible futures

Kelsier showing up somewhere, laying waste, and leaving. Happens twice I believe.

In the mean time... please don't".)
