Oathbringer chapter 15, basically:
Adolin: We need to talk about a difficult topic.
Shallan: OH NO HE'S BREAKING UP WITH ME!
Adolin: You know how I had you try spicy food?
Shallan: .... Oh storms oh no he's going to ask me about me murdering my parents!
Adolin: You have a sword! I have a sword! We can be sword buddies now!!! Yay!!!
(I just think it's really silly that Adolin wants to teach his gf how to use her magic glowy weapon, leads into it by bringing up spicy food, and she assumes it's about parricide. Adolin: you know how food can be hot? Shallan: is he about to say he doesn't think I'm hot anymore or is this a lead-in to how hot the tears were on my face as I sang my father to death? Adolin: knowledge of the blade is also very hot. Shallan: Oh. Oh, what?)
