Mabon had clearly seen what had happened between the diviner and his nephew even though his mind was slow at processing what his eyes were seeing.
Lily Malum had sprayed blood on Seth's face making the fluid enter into his mouth, his eyes and even some seeped into his nose. It wasn't a pleasant sight to behold. Her body began to tremble and at the same time, it began to swell as well. It seemed like she was about to explode, that was how large her body was getting. To say it was an eye sore wold be the biggest understatement.
However, Seth had changed quickly, it seemed like he had done it in a flash, and he engulfed Lily with his body and his black muscle-like wings. No one could see Lily Malum again because of how Seth had covered her. The only part that could be seen was her feet which had swelled also making it look like it was an elephant that was standing with Seth.
