In no particular order, I just like numbered lists:
1) Taln interlude in WoR, the servant says he crossed paths and rode with Wit. Wit's insult about the ride registering at around 4-5 blows to the head with a rock was hilarious to me.
2) The sequence from Kaladin training with his mangled leg to "Stretch forth thy hand!" and Kaladin's swearing the second oath. Whenever I read it I'm torn between laughing and crying.
3) Chasm scene in TWoK when Kaladin picks up a spear shaft and performs the kata exercise. You can almost feel the shift in the bridgemen.
4) Amaram's apology scene. It was so satisfying to see him finally subject to the truth, and it was a huge relief to me that Kaladin didn't end up killing him in the name of vengeance. Also, the whole part with Kaladin assuming he had to apologize and Dalinar saying, "Not you, son," melted my heart.
5) In TWoK, when Navani finally gets Dalinar to see her as a person rather than a threat. The cracks in her facade added a lot of depth to her character.
6) Lopen's POV at the end of WoR. Proved once and for all that 1) Herdazians are all incredible people, not just Lopen and 2) Lopen will not ever underestimate himself, and rightly so.
7) Every scene with Lift in it. She is a light to all the world.
8) Beginning of WoR, when Jasnah tells Shallan she apologizes too quickly. Shallan's reply is embarrassingly funny to me: "I'm uh, indignant?"
9) In TWoK, when Kaladin fights Eshonai in order to help Dalinar. That image is frozen in my mind, and makes me wish I had even an inkling of artistic ability
10) In WoR, when Kaladin and Szeth enter the storm while fighting. I'd been waiting for another Kaladin scene inside a Highstorm, where he was less helpless and was able to use the stormlight provided to survive. Reading that scene felt like exhaling a long-held breath.
(Obviously, Kaladin's my favorite character)
