The Long Lost Winchester: The Hunt Continues

Sam, Dean, and Liv lean up against baby with their head turned to the heavens as angels rocketed to the earth. Metatron had done it, he'd cast the angels out of heaven. The Winchesters couldn't believe their eyes. Liv turned to Sam, his breathing lowered and slowed. He was fading, quickly.
Dean, and Liv rushed Sam to the hospital there was little time for him. The Doctor came in, sorrow crossed his face. Sam wouldn't make it without a miracle.
Liv and her brother asked Cas for help, there was no answer. Suddenly a new angel appeared, Ezekiel, he offered to help the Winchesters by healing their brother. Little did they know, he was not who he claimed to be.
