@Nameless sorry I wasn't able to respond earlier, I don't know if I'm just unusually emotionally dead or if everyone else forms unreasonable emotional attachments to characters, but I'm neutral to most of them, in fact in the entire Cosmere I can only say I truly like Hoid, Lift, Szeth, Kaladin, and Dalinar and Kelsier but the last two only a little bit. And I only truly dislike Shallan. Lirin hasn't done anything to deserve any particular reaction from me.
Lirin doesn't know Kaladin like we do, he probably only has seen him a handful of times since Oathbringer, and for that Kal will put on a brave face. Roshar is way behind us in terms of mental health, Lirin was not making an attack, at least not intentionally.
