Although I couldn't figure out what exactly was going on with the father-daughter relationship of these vampires, how could people who are hundreds or thousands of years old still be in their rebellious phase, engaging in a cold war or something like that. But it was good that K was saved, and Li Pan didn't have any place meddling in other people's family affairs. After all, strictly speaking, he was just K's personal blood tofu, even his title as a "Knight" was self-proclaimed.
But at least when K had used the Holy Grail to basically change her blood, she had recovered consciousness and was back to looking pretty and beautiful.
The other Night Walker Knights didn't take the opportunity to cause trouble or try to snatch the Holy Grail. After all, a whole squadron of knights hadn't been able to take it before, so what could a few of them really stir up? They just loaded K into a life pod and retreated for treatment.
