In "The Final Empire", eventually Ham and Kelsier learn to understand and speak in Spook's dialect. The following conversation ensues.
Spook: Niceing the not on the playing without. Breeze: I have no idea what you just said, child. So I'm simply going to pretend it was coherent, then move on. Kelsier: *rolls eyes* Losing the stress on the nip. Notting without the needing of care. Spook: *nods* Riding the rile of the rids to the right. Breeze: What are you two babbling about? Spook: Wasing the was of brightness. Nip the having of wishing of this. Kelsier: Ever wasing the doing of this. Ham: Ever wasing the wish of having the have. Brighting the wish of wasing the not. Breeze: *to Dockson* I believe our companions have finally lost their minds, dear friend. Dockson:Wasing not of wasing is.
From Hero Of Ages, Elend and Ham have just decided not to send a force of 40,000 Koloss to attack Fadrex City, which would likely have resulted in the deaths of most of the population
When Elend does something stupidly risky in the second book:
Elend: Stay here, wait to see if I get back. If I don't, tell Vin what happened.
Ham: Sure, I'll tell her. Then I'll proceed to remove her daggers from my chest.
After Kelsier comes back from destroying the atium crystals in the Pits of Hathsin:
Ham: Where were you? We've been worried sick that you were out doing something...well, stupid.
Breeze: Actually, we took it for granted that you were doing something stupid. We've just been wondering how stupid this particular event would turn out to be. So, what is it? Did you assassinate the lord prelan? Slaughter dozens of noblemen? Steal the cloak off the Lord Ruler's own back?
Kelsier: I destroyed the Pits of Hathsin.
Breeze: You know, you'd think that by now we'd have learned not to underestimate him.
Vin, on her mysterious acquisition of a ball gown in the last book:
Elend: Seriously, Vin, the army's tailors are good, but there's no way that dress came from materials we had in the camp. Where did you get it?
Vin: It's a mystery. We Mistborn are incredibly mysterious.
Elend: Um... I'm Mistborn, too, Vin. That doesn't make any sense.
Vin: We Mistborn need not make sense. It's beneath us.
This, incidentally, is a Call Back to Kelsier's use of the same explanation in the first book.
From the same scene, Ham finally finding a captive audience for his philosophical ponderings. It's easy to imagine that only the convenient scene transition prevented a Big "NO!".
Yeah, that was hilarious. Especially because the captive audience was Cett, who absolutely hated listening to Ham's philosophical ponderings. I believe the exchange went something like this:
Ham So, you can't go anywhere unless someone moves you, right? [Cett is a paraplegic.]
Ham Well in that case, I have some interesting philosophical questions I've been meaning to discuss with someone...
When Elend told Vin that killing his fiancÚ, God, brother and father, in that order was a homicidal hat trick.
In the first book, Kelsier's crew has a meeting in the beginning for starting to formulate a plan to take down the Lord Ruler. Kelsier gets them to list the problems they're going to have to deal with and write them down on the blackboard. After everyone lists a lot of problems, Yeden adds something pessimistic along the lines of "The fact that this plan is doomed to fail and we're all going to die," and Kelsier writes on his list of problems they have to deal with, "Yeden's bad attitude."
"I am, unfortunately, the Hero of Ages."
Cett has a tendency to throw things at Breeze, like insults. And knives.
