Spoiler: Knight identity
I'm replaying chapter 1 (full pacifist this time, in order for full pacifist chapter 2), and I realized...
During the fight with King, he talks a good bit about "my Knight." The fact that Kris is right in front of him makes me think those theories on Reddit about Kris being the Knight are wrong.
Also, totally unrelated, bit of a bummer you can't keep the hot cocoa or the not-Sans phone number, going from ch 1 to 2.
