"My Lord!" Sam screamed, rushing forward as Cass kept heaving. More black, tar-like liquid poured out from his mouth. Cass wondered where the hell it was coming from as he continued to heave until his diaphragm felt bruised, and his muscles convulsed. Byron was holding him up, while Sam wiped his brow.
"We need to call for a Doctor!" Byron whispered tensely, but Sam shook his head. His already pale face went whiter, the freckles on his face in stark contrast as he stared down at the black liquid pooling at their feet. Cass fought for his breath as Sam let out a shaky exhale.
"No. A Doctor won't help." Sam muttered. It was only seconds after that, that the liquid began to sizzle, smoke rising from it as it caught on fire. Sam and Byron yanked Sam back, pool flaring to life as Byron and Sam dragged Cass back. Sam had a grim look on his face, while Byron was in shock.
