John took a long breath, he wasn't ready to tell his father the news. Just when they finally got back together and were creating the family they always wished for Ethan to die.
He died for a good cause, and John deeply down knew he wouldn't be able to fight the protector. When banshees existed only 1 out of 100 banshees had a protector. They had the powers of banshees but more intensified and the only way to fight them was to burn their body and at the same time ripe their hearts off which would be a proper suicide.
John felt so shaken and sad for the situation he was in that he could barely believe that happened, he felt like it was too sad to be real and he wished with all himself he would wake up from that nightmare.
Unfortunately, it wasn't a nightmare but it was the brutal truth.
