The devil within

Basically Dan and Phil die and become angels but the devil loves to send disguised demons to heaven to find the purest angels and make "friends" with them,kidnap them, bring them to hell, and force darkness into their soul. Basically that's what happens to Phil which results in an extremely worried Dan and a not so like Phil, Phil.

I suck at writing but I liked this idea and had to write it read if you like.
