Piper Halliwell becomes pregnant with Wyatt in Season 4 of "Charmed." Specifically, her pregnancy is revealed in the episode titled "Something Wicca This Way Comes," which is the 18th episode of that season. Wyatt is born in the Season 5 finale, "Forever Charmed." Piper's pregnancy is a significant plot point that adds to the series' themes of family and legacy.
Piper is from Charmed, and Rachel is from Glee.
I am very sorry to tell you this but there is no season 9 in charmed season 8 episode 22 all that happens is that you see piper's kids and phoebe and her boyfriend and then you see piper telling a story to some kids.
