Having to undergo the evolution process right now was akin to torture, in more ways than one. First of all, the level of physical pain Quinn was experiencing was immense. As it drained the Nest Crystal's energy, the vampire felt that his body was on the verge of exploding, only a single tiny step away from his demise.
Nevertheless, Quinn instinctively knew that it was doing so to push his body towards the next stage. Every part of his body, his cells, muscle fibre, bone structure and so on was getting pulled apart and rearranged into a more optimal way. All of it got broken down and rebuilt from the ground up… only to be broken down again for the process to start all over again.
And yet this wasn't the worst part of it. No, while the vampire had to endure this near-death experience, he was forced to watch the Dalki leader wreak havoc on the people on his side. Quinn felt helpless as he felt Graham go on a killing spree.
