Oh man, I know I'm way behind on reading this story, as I just recently came on board, but I want to pause to comment anyway.
The friction between Dave and Jae was heightened by the impending fight they were preparing for, and it is ironic that Dave considered the fight-for-survival different in these two circumstances. However, learning that your partner has killed people, regardless of circumstances, can be jarring. I don't entirely blame Dave for his initial reaction, but he should have been a little quicker to make amends. Hopefully, he still can.
Riveting chapter, tim.
