spoilers:end of spoilers
Kaine: Die!
Ben: Let's talk about this.
Kaine: Die!
Ben: What if we talk about this while sword fighting?
Kaine: Die!
Ben: Okay, I have trapped you, now can we talk about this?
Kaine: Die! BAM
Ben: You shot me! I'm trying to save a little girl's life!
Kaine: Okay, I will let you cure her. Then, Die!
I do hope Kaine sticks around permanently, his and Ben's interaction is just too fun.
