Paige is introduced into season four as the fiercely independent younger half-sister of the female leads, Prue (Shannen Doherty), Piper (Holly Marie Combs) and Phoebe Halliwell (Alyssa Milano).

In the eighth and final season, Paige marries a human parole officer named Henry Mitchell (Ivan Sergei).

In addition to the television series, the character has also appeared in numerous expanded universe material, such as the Charmed novels and its comic book adaptation.

Producers then decided to kill off the character of Prue and replace her with a long-lost younger sister in favor of having "a fresh face" join the series.

"[2] On casting McGowan in the role of Paige, Kern admitted, "Our personal hope was to find somebody that would be of Shannen's calibre, that would have the sexiness, the edge and the range.

[3] This is made possible after it is revealed that she is the daughter of Patty and the Whitelighter Sam Wilder (Scott Jaeck), making her a "sister-witch" to Phoebe and Piper.

[25] Also this season, Paige befriends federal agent Kyle Brody (Kerr Smith),[26] and the two eventually grow close over their mutual investigation of The Avatars, powerful beings who are neither good nor evil.

After initial hesitation, Paige and her sisters join sides with The Avatars in their plan to turn the world into a utopia against the warnings of both Kyle and The Elders.

[27] In late season seven, in episode seventeen "Scry Hard", Paige grows tired of being cooped up in Magic School and desires a reprieve from her duties as headmistress.

[29] The following episode, "Little Box of Horrors", The Elders manage to convince Paige that her continued quest for a life outside her role as a Charmed One stems from her destiny as a future Whitelighter.

[30] In the episode "Freaky Phoebe", Paige takes on official Whitelighter duties and gains her first charge in a witch named Mitchell Haines (Seamus Dever) who has the power of superhuman speed.

[31] In the season seven finale, during a suicide mission to vanquish Zankou, Paige and her sisters fake their deaths in order to escape the constant threat of demon attacks as well as police and government investigations.

[32] In the eighth and final season (2005–2006), Paige takes on the false identity of Jo Bennett (Christina Ulloa) and attempts to live a normal life free of magic.

[33] This proves to be impossible, as Paige hears the continual call of a new charge, a telekinetic witch named Billie Jenkins (Kaley Cuoco).

[35] After a courtship, which involves Henry discovering Paige's secret identity as a witch and whitelighter, the couple get married in the episode "Engaged and Confused".

[36] Later in the season, Paige discovers that her charge Billie and her sister, Christy Jenkins (Marnette Patterson) are the ultimate power The Charmed Ones must defeat to save Leo from the Angel of Death (Simon Templeman), but she has reservations because the women are human and not demons.

Due to her Whitelighter side, Paige's telekinetic power carries aspects of teleportation, although she still showcases the ability to impart momentum on the objects she orbs allowing her to throw them across distances.

For instance, in the season six episode "Hyde School Reunion", Paige orbs demonic acid by using the vocal call, "Icky stuff".

[53] In the Charmed comics, specifically Issue #3, Innocents Lost, Paige develops a new power in the form of a reinforced force field made up of orbs.

[43] Paige displays the ability to encase others inside of her force fields, without being within them herself, when she uses her new power to contain the explosion caused by the resurrected Source's destruction in the tenth issue of the comic series, Three Little Wiccans.

[55] Because Paige's father, Sam Wilder, is a Whitelighter, she has inherited a number of powers associated with this race of guardian angels which include Orbing, Sensing, Glamouring and Healing.

[30] In late season four, it is revealed that Paige has acquired the ability of sensing, a supernatural power which grants a Whitelighter a magical awareness of a charge's location and physical well-being.

"[64] In his review of the fourth season, Jeffrey Robinson of DVD Talk felt that Paige fits right in with the sisters and noted that her addition changed the character dynamics of Piper and Phoebe "in a good way.

"[65] In another review of the fourth season, Leigh H. Edwards of PopMatters added that the addition of Paige was "contrived and clunky", but welcomed the idea of McGowan joining the show as a witch "since she has major goth cred as Marilyn Manson's former flame.

"[66] DVD Verdict's Cynthia Boris wrote that McGowan brought "a youthfulness" and "a fresh viewer perspective" to Charmed, further noting that "fans have come to enjoy her presence on the show.

[69] A writer for MovieWeb praised McGowan's performance for delivering a "great and relatable character", noting that "She gets all of Paige's own quirks and emotions and the feel of adjusting to things down really well."

[70] Rob Lineberger of DVD Verdict commented on McGowan's acting in the fifth season, noting that she "clips off the end of every sentence, often growling more than annunciating her lines."

"[72] BuzzFeed's Jarett Wieselman commented on Paige's outfits, noting that many of the episodes featured her, along with Phoebe, wearing "a series of progressively revealing and ridiculous costumes in the name of vanquishing.

"[73] Tariq Kyle of Hypable.com wrote that the funniest moment of Charmed was in the season four episode "Hell Hath No Fury", when Paige's breast size increased "by a ridiculous amount.

[79] In his review of the television series Witches of East End being too similar to Charmed, Christian Cintron of Hollywood.com noted that Mädchen Amick's "snarky, sarcastic" character Wendy Beauchamp "channels Rose McGowan's Paige Matthews.
