Oscar Miller, the one who escaped the net, was ultimately a disaster that Carson Flores had to personally crush to death.
The entire Miller Family was obliterated overnight, and from the favorite child of the heavens Oscar Miller degenerated into a lost and homeless dog—he could not possibly not hate, not possibly forgive.

Having clarified Oscar Miller's whereabouts, Carson Flores also breathed a slight sigh of relief.
