Charmed - Episode 609 - Little Monsters

After vanquishing a Manticore demon, Piper, Phoebe and Paige become foster parents to its orphaned half-Manticore infant. Knowing that danger is near, Chris urges the girls to vanquish the baby, but they believe that if they raise the baby with love, it will not become evil. While waiting for the Manticore pack to come for the baby, Piper and Phoebe are taken by surprise when a Beast (guest star Seth Peterson, "Providence") tries to kidnap the baby but ends up taking Piper instead. Piper learns that the Beast is the baby's father and helps reunite him with his son. Meanwhile, Phoebe surprises her boyfriend Jason (guest star Jason Dean) when she blurts out her true feelings, and Paige gives Darryl a superpower.
