John must figure out why thousands of people across Brooklyn fall into a mysterious coma on Constantine. "Quid Pro Quo" is the tenth episode of the show's first season.
Chas: You're the only one I trust with her John. John: Well whatever this is mate we're in it with you alright. So, you want to tell us what happened? Chas: I found her on the floor bleeding. We raced here I saw six other patients with the same symptoms. They're calling it a coma, but this isn't like any coma I've ever seen.
John: If you need to disappear, best place to do it is here. Zed: All the protections you've used, they're not enough. He'll never stop searching for me. John: You're yet to flinch in the face of the underworld. Why are you so afraid of a man from this one? Zed: Because he's my father.
