Paige Matthews is the youngest half sister to the Halliwell clan, her parents being Patty Halliwell and Sam Matthews (Patty's Whitelighter). As a half whitelighter, Paige's power of telekinesis naturally resembles one of that of a whitelighter. Like Prue's power, it is the power to call for objects (which could get pretty useful) but instead of seeing the object visibly zooming towards you, it orbs. Paige's orbing powers also saved her life many times when deadly energy volts and fireballs come her way. Paige takes over Phoebe's place as the youngest sister and watching her is just like deja vu in season 1 where Phoebe was the irresponsible and carefree one. New to her craft, she learns the hard way how to be a witch. Some may find her pretty much money minded especially during the episodes where her apartment got torched by the Enchantress (A Knight To Remember) and she despaired ("Don't think I'll get insurance coverage for this...") Paige had started off as the cowardly, irresponsible sister but I'm sure she'll adapt to being a Charmed One soon.
