I still follow it. You should have known that Cole wouldn't lose demonic powers forever. He made a deal with the woman to save Phoebe and her sisters from death by the Source. She gave him some powers from some ancient demonic power that had defeated the Source before. Cole killed the Source but also received all of the Source's power. Now it seems like the Source is in control of Cole, but Cole is still inside of there. I do not believe he is Balthazor anymore though, but he is far more powerful than before.
