Andy Trudeau (played by Ted King) is a detective for the San Francisco Police Department.
He was introduced in season one as the Halliwell sisters' childhood friend, and Prue's high school sweetheart and first love.
In season six, Chris reveals that he is actually Leo and Piper's son and that he traveled back in time to prevent his older brother Wyatt (Jason and Kristopher Simmons) from growing up to be the evil dictator he becomes in the future.
However, in season five Cole escapes The Wasteland, due to him stealing vast amounts of powers off other dead demons, and forces himself into the sisters' lives again.
Cole never regains their trust and although he attempts to dedicate his new life to being good, Christopher Perry Halliwell (played by Drew Fuller) is the second eldest son of Leo (Brian Krause) and Piper (Holly Marie Combs), making him a half-witch and half-whitelighter.
One of the reoccurring struggles for Paige is finding an identity for herself outside of her role as a Charmed One.
In the final season, she marries mortal parole officer Henry Mitchell (Ivan Sergei).
Because of her free-spirited nature, she often comes into major conflicts with Prue (Shannen Doherty), but the two eventually mend their relationship.
