I loved this series, just binge-watched it last night. Cannot WAIT for Season 2; the ending was chef's kiss. Couple questions though:

Spoiler!

Why did Cooper's character not get an explanation as to why he turned into a ghoul? Do ghouls live long because they're on meds (similar to how Thaddeus' character healed so quickly with the meds he huffed and then they called him a ghoul after he took the arrow to the neck and survived)? Also, I'm assuming ghouls have no noses because cartilage wouldn't last that long?
