Isabel got in her car and started the engines.
Isabel jumped up and screamed. She looked behind, over her shoulder, but there was no one to see.
“I’m going crazy” she mumbled and she rubbed her eyes. She hadn’t been sleeping very well, not with everything that was going on.
“You’re not going crazy” the voice commented. “You can’t see me, but you can obviously hear me. My name is Anna and I’m an angel”
Isabel shook her head. This was impossible.
“I see you have trouble believing so” Anna noted. “However, I need you to get over the shock and listen carefully. You want to find Cas. I can help you with that. Take a look in your rear view”
Isabel checked her rear view mirror and saw Heather lying on a table, dozens of syringes pierced in her naked body. Cas and Meg were standing by her.
Isabel looked behind her again, but again there was nothing and no one to see.
“Before you go you need to call Dean and Sam Winchester. And one more thing, do not touch Castiel. Take the girl, but leave Cas to me. The most important thing is that you separate them”
