At the jail :
A cop walks up to Phoebe's cell.
" Well, Ms. Halliwell. Your free to go, Three people just turned themselves in for the murder of your father."
Phoebe's gathers her things and walks out. She calls a cab, then goes back to the manor. Walking into the manor, Prue and Phoebe hug her.
Piper speaks.
" Oh Phoebe. We were worried about you. Welcome back honey.
" Yeah, welcome back Pheebs."
" Glad to be back."
Two weeks later :
All three sisters are watching the news.
" It has been announced today, that the three people who murdered Victor Halliwell will receive the death Penalty by lethal injection."
Prue, Piper, and Phoebe all smile with joy at the conviction.
" The dates are January 2nd,3rd, and 4th of this year. They will not be allowed parole."
Three months later :
Prue, Piper, and Phoebe sit in the observation room of the execution chamber on Jan. 2nd.
"Do you have any final words ?"
" Yes, I do not regret my actions at all."
Seven minutes later the ex demon, is pronounced dead. Prue, Piper, and Phoebe leaves satisfied of what they just seen. Maybe now they could move on.
