complex emotions

The thin, quick biped- that one that had been presented to the phile before its escape from the wheeled cage- that one was its primary adversary. The phile had sensed their kinship even then, and it knew now that the other killer recognized it as well. It resembled the other bipeds superficially, but plainly this one was a breed apart- like the phile, a creature bred for the art of killing.
...
The destruction of its brood infuriated the phile, but now it realized this atrocity had only been intended to goad it out of hiding and back into the blood game. Nonetheless their must be vengeance for this- payment in kind for the slaughter of its offspring.
