Mr. Guinn had already subdued Finn Taylor, so it wouldn't take much effort to kill the latter. Yet, the former was now asking his boss to let the latter go!
"Why? Give me a reason." Melanie Taylor didn't necessarily want to kill Finn Taylor, but she wanted a reason to let him off.
"I'll tell you the reason later. Let him go first—this isn't a discussion. If you refuse to listen to me, I'll stop you myself."
Melanie Taylor hadn't expected the old man to be so stubborn. 'He's standing up for Finn Taylor? Has he switched sides? But that's impossible. Mr. Guinn is very loyal to our family, so there must be more to this. I better not ask him anything about it for now. I'll just do as he says and let that man go.'
"Finn Taylor, you're really lucky. I'm going to let you go today."
Finn Taylor had no intention of fighting with the other. He was injured, and so were Lancelot and Guinevere.
