Outside of the main base, Quinn was waiting with Sil, Shiro, and Layla. Using a bit of his own Qi abilities, Quinn was able to settle the wild Qi that was affecting her body, allowing Layla's natural Qi to fuse with her injured cells allowing her to start healing.
With the foreign Qi expelled, she was soon enough good as new. At least physically speaking, mentally was a different story. Honestly, Quinn didn't really want to take Layla in her current state. He was deeply concerned, since it was clear there was something that she hadn't told them, and he knew well that she had a history with Pure who were also out on the hunt for the Demi-god tier beast.
The reason why he allowed her to come along, was because he was worried that she would just go off on her own once more, if she was left behind. There was no guarantee there would be Logan or someone else rescuing her next. It was far better off being next to him than away.
