User blog:NickHunter26/Where was Jesse Turner ?

First of all: i'm french. So excuse for the bad english. Okay, i know that the writers have probably forgot him but in the logic of the series it makes no sense: Jesse is the eighth more powerful person in the all Universe: 1. The Darkness; 2. God; 3. Death; 4. Michael; 5. Lucifer; 6. Raphael; 7. Gabriel; 8. Jesse (not counting soul-enhanced Castiel and tablet-enhanced Metatron). And as Lucifer come back on Earth, he probably get his nigh-omnipotent powers back. So why they didn't call him for help in the final battle ? He could have make the difference. Explanation ?
