What is Qi?
After seeing Layla's body lying on the floor like that, Quinn didn't rush over, he wasn't filled with rage. Instead his mind had gone completely blank. It was as if he didn't really understand what he was looking at, nor how something like this could have been possible.
'No. No, I gave her a command, didn't I? I told her not to get involved. So how did it become like this?'
Quinn was unaware of everything that Layla had done beforehand. Knowing that it was quite possible her mother would die in this fight, she needed to make sure that wouldn't happen, not just for herself, but for Quinn as well.
If Layla had to pick who she sided more in this fight, Quinn or her mother, it would have to be Quinn. Whenever she thought about this, this was what her mind wandered to.
And at the end of the day, not only did Layla not want her mother to die, she also didn't want Quinn to become a large target of Pure. He wasn't ready for that yet.
