Imaginary Friends

The Charmed Ones discover that baby Wyatt's new "imaginary" friend is actually the demon Vicus, who is trying to win Wyatt's trust to turn him evil.  Piper casts a spell to be able to understand baby Wyatt, but inadvertently brings 25-year-old Wyatt back from the future.  When Vicus places a curse on baby Wyatt, the effects are seen immediately in future Wyatt, who physically transforms into a darker version of his previous self.  Evil and powerful, future Wyatt kidnaps baby Wyatt so that the sisters can not convert him back to good.  Meanwhile, before future Wyatt leaves, he gives Phoebe, Paige, Piper and Leo an insight into the future.
