Andy is not coming back.
Bane will probably not come back this season because Antonio is committed to other projects.
Cole will be good in the end. (Yeah!!!!!!)
Phoebe and Cole's relationship will not work in the end. (No!!!!!!)
Piper is expected to get her new power in May. It will have to do with time manipulation.
My guess is it will be a offensive power rather than a defensive power.
Phoebe and Prue will not get any new powers this season, but the power to fight will grow.
The Triad is not dead.
Cole will be sticking around to work things out with Phoebe, but the source will eventually find him and it looks like he'll be meeting them soon! There is something big happening with Cole towards the end of the season but it's not the way that you would think...it's hush-hush right now!
season finale-It'll be a cliff-hangerI t revolves around the source
Has Cole been turned completely good?
No, he'll always have some evil in him that'll never go away and so does
Phoebe. In episodes to come, the Source will take advantage of Phoebe's dark
side and try to kill Cole 100% when he finds out he is still alive."

"Q: When do the girls' contracts expire?
A: Season six, and ALYSSA IS NOT LEAVING!

Q: Back when Cole was working for the Triad, he had a deal with them. If he killed the Charmed Ones, the Triad would give him back...something. The writers have never said what that something was. Any ideas?
A: It wasn't?? I know it was mentioned in one of the scripts (somewhere...) Well, it was suppose to be if he killed the sisters, he'd get to be mortal.

Q: Will someone be pregnant in the season finale?
A: That is a rumor. A very good one too that is a possibility. After going against the source they'll need new story lines and what better one than someone getting pregnant. Please do not quote me as I am just speaking from what I think will happen. But someone MIGHT, MIGHT, MIGHT take a pregnancy test at the end of the season but you won't who because it would be part of the finale.
