The Third Man

Cas is back! This Friday's episode is definitely gonna be exciting. I know, I know. They all are. lol. But it's been lonely without Cas, and I definitely want to know what he's been up to since the finale. **SPOILER ALERT** (just in case) 


** Especially after put Dean and Bobby back to normal**


The official summary, thanks to IMDB, says that Sam and Dean call on Cas to help them out with this job involving a lot of police officers who have been dying mysteriously by the same the Plauges of Egypt. If you don't know them. There are 10. 
1) Plague of Blood 
2) Plague of Frogs 
3) Plague of Lice 
4) Plague of Flies 
5) Plague of Livestock Death 
6) Plague of Boils 
7) Plague of Hail 
8) Plague of Locusts 
9) Plague of Darkness 
10) Death of the Firstborns


Cas being Cas... finds out that the Staff of Moses has been used to kill these police officers, and that all of God's weapons have been stolen, so they go try to hunt down the thief, and apparently an "old enemy" comes back. 
Any thoughts who it might be?


Can't wait until this episode!
And also remember. Supernatural Magazine Issue 20 is released October 13th.
