So, I just noticed that when Susie and Noelle are talking by the bed, while Kris is trying to keep the soul from the guitar, Kris blushes when the girls are talking about him being good at flirting attacks, and also when Noelle is remembering the Ferris wheel.
There's actually a normal teenage boy beneath that angsty destroy-the-world-with-darkness plan.
It's kinda cute.
