Sounds like there much, much to catch up on with these two "Friends" :P but as it sounds, Dee isn't too interested to rekindle the friendship with Casper. xD Dispite the fact that dee just hates him :P and Casper likes to annoy him a lot :3 Luckity dee is safe cause ghosts can't take Possession Demons and thoughs are in the underworld :3
Dee Belongs to Kree
