Yeah I was thinking the same. He also gave him some blood when he was chocking Fabian to activate his power, so I think it could be that K is able to keep it under control, as he was saying he left his guard down when Jerome appeared.
He said it's about how he is guiding him. I think he always guide him to protect him from the penalties. Since he is overflowing with that power, it doesn't bother him to always do it but he had to be extra careful to keep him from experiencing the penalties, too.
Yea.. that's wat I thought to.... Since K is strong. He just had to put more effort and stayed on guard while guiding to stop the penalty
So maybe because I read it in one go, but there was a thing that I noticed. So Fabian can experience the hallucinations when tasting Konrad’s blood, then wouldn’t him experience that when they did the bloodbound? Like the hallucinations happened way before they discussed it. Maybe I missed out on sth but the story was still enjoyable just some details that was confusing
