Yeah, it was an exciting, scary, heart pumping chapter to write. Warren was indeed the hero again. His deire to help proved right as it happens, but he did take a hell of a chance. I honestly believe Kellar reached Reznick's neck in time, so he would have saved Tobyn. The only shot fired was Warren's, so Reznick wasn't quick enough. What mattered to Kellar, though, is that Warren got the credit.
Yes, if Reznick had survived with the copper knowledge, their advantage would have been over. Thank you, sir!
