Question: Why does Leo have powers in this episode that we never see him use again? Levitating for example, reheating a cup of coffee. The refilling the water could be explained by his normal white-lighter powers. I think it's probably because the writers changed their minds about what exactly would constitute white-lighter powers. However how is this explained, in canon? Leo as far as I remember doesn't levitate again, neither does Paige or Chris. It isn't as far as I remember established as a white-lighter power.
Answer: He does levitate in the 4th season finale, when Piper allows him to do so (despite her not wanting to jinx their new peace by doing magic) in order to properly place a framed picture.
Question: Later in Charmed they bring the so called "cleaners" in episode 6-2 when Wyatt conjures a dragon and magic is exposed. Why didn't the cleaners appear earlier in this episode when Piper and Prue exposed magic?
Answer: When the cleaners first surface in season 6 it is mentioned that usually the girls have been able to clean up their own messes (as seen in season 3 episode 22 when Phoebe turns back time thus concluding in the death of Prue).
Question: Why do the sisters keep changing their appearance throughout a few episodes? We're there issues with replacement actresses that caused the changes? Victor references that they keep changing identities but there is no good explanation as to why.
Answer: You have to watch the previous episodes but basically they are pretending to be dead. They cast a spell to change their appearance in which only Victor and each other can see them for who they are. Their appearance keeps changing because they can't decide what to look like.
Question: How does Chris still have his powers when he travels to the past, but the witches did not when they went to the past?
Answer: With Chris being from the future (and being half-witch, half-whitelighter), he must know about the fact that his aunts can't use their powers in the past. Therefore, he would think to write an advanced spell so that his powers can be used.
Question: What is the song that plays immediately after the opening credits/theme, over the shots of San Fransisco? [At least in the version on Netflix in the UK - other versions seem to have "Torn" by Natalie Imbruglia]. The lyrics go something like this: "We hope and we pray for a break, that the weather around us might change, that hope just fell asleep in the hole where burdens keep pulling and pressing the weight of the problems in life that we face, but faith's so incomplete."
Answer: I get the impression that it is a studio band doing a "sound-alike" piece of music that may not have ever been released but was done just for the show. I'm not sure it has a title or can be found anywhere outside of the episode.
Question: When Cole first appears in Charmed, the first time Piper uses her freezing power in court, Cole doesn't freeze but in later episodes he does. Why?
Answer: Because during this scene, Piper was only freezing the Innocents in order to draw out who the demons were. She has the ability to control her power to freeze only what/who she wants at a given time so when she was using her power here, all the demons would remain unfrozen as she intended. Cole knew she and her sisters were witches and what powers they had so he knew Piper could freeze. Since Piper was only focused on freezing the innocents, Cole was just pretending to be frozen in order to pass off being one. Remember, at this point, they do not know Cole is a demon.
Question: How did the charmed ones save themselves from dying in the nexus with Zankou when everyone thought that they died?
Answer: Because they used the spell Prue developed so the others could use the astral projection power. It was their astral selves and those can't die.
Question: Piper and Leo switch powers so Piper can heal him. Leo ends up dying but Piper finds the trigger to the healing power after his death. How come she is able to bring him back to life when in later episodes it is revealed that Leo's healing power cannot bring the dead back to life?
Answer: It probably meant that it couldn't bring humans back to life, magical or not. As a Whitelighter, Leo is technically not human because he's already died as a mortal. The only way to heal a Whitelighter from the poison that "kills" them is to be healed with the healing power of a Whitelighter.
Question: In this last episode, when the sisters are writing about their personal lives and they show the future kids they will have, Piper is shown giving lunch bags to 3 kids. It shows 2 boys and 1 girl. Why is that? Did she have Melinda? If so, why when older Piper and older Leo are going up the stairs they only show pictures of the boys, Wyatt and Chris? No pictures of the girl shown anywhere.
Answer: It was most likely just a montage for the fans as a final goodbye. Also, prior to the episode, Melinda was only seen once whereas Wyatt and Chris were in multiple seasons/episodes and therefore played a bigger part in the story.
Question: Is there any reference to other witches, besides the sisters, that have vanquished a source? Or are they the only witches ever to be powerful enough? The source does have the ability to be reconstituted with a spell in the grimoire.
Answer: The sisters are the only witches that have been powerful enough to vanquish the source, gaining their strength from the power of 3.
Question: Why can't Paige heal people? I've only ever seen her heal about one person. Is there any particular reason for this?
Answer: Chris explains in the episode "Valhalley of the Dolls" that healing is extremely difficult, and can only be done by accomplished Whitelighters. Paige has only had her powers for a few years and is only half-Whitelighter, so at first, she can only heal people when Leo helps her. In Season 8, when she realizes she loves Henry, she unlocks the trigger to Healing (as explained by Leo at the end of season 1), and is able to heal others like a regular Whitelighter from then on.
Question: Just wondering why we don't see exactly how Prue dies and how Cole and Phoebe make it back from the underworld at the end of Season 3. Is it because Shannon Doherty left the show and they had to try to fill in the gaps?
Answer: Prue's death was never shown because the show wasn't sure it would continue after Season 3. The cliff hanger left the audience believing all three sisters would die (Prue and Piper at the hands of Shax, and Phoebe by the Source). The show was picked back up for 5 more seasons, but Shannen left. Rose was hired on to be half sister, Paige, so as not to recast Prue, and once they began filming, they didn't have Shannen to film an explanation (they also couldn't use her in later seasons as she owned her image, and it was illegal for Charmed to use it without her permission. This is also why you don't see pictures of Prue in the series finale, and why the shot shot of her from the back in "Cat House" was a body double). So instead what we received was Piper angry at Leo for healing "the wrong sister" as he healed Piper first (from the damage we saw inflicted in the last episode of season 3) and it must have been too late to heal Prue - unfortunately we just weren't able to see the immediate after effects of Shax's attack.
Question: How is it that when Piper and Leo go to the past before Phoebe is born, Patty already knows about "the charmed ones"? I have been under the understanding that they are the only ones in existence, so how does she know about the concept of "The Charmed Ones'? Was it a prophecy or something?
Answer: Yes, Melinda Warren prophesied that each generation of Warren witches would grow stronger than the next, culminating in the arrival of three sisters. Each having one of her powers.
Question: How come in this episode when Andy asks Pru if her kids will inherit powers she says "If they're girls, they will"? Why will only the girls inherit their powers? We know this is not true, both Wyatt and Chris have powers, Wyatt has them even before he is born.
Answer: Honestly that was Pru when she was inexperienced in the craft. she didn't understand that men could be witches too because "Grams" made her believe so. In the the episode 'Secrets and Guys' the sisters discover that "Grams" was wrong and that men could be witches too. Later in the series the sisters even acknowledge this fact and use the term male witch throughout, eg. the season three episode titled 'Blinded by the Whitelighter' when Phoebe has a premonition of a male witch being attacked by the evil warlock Ames, played by S. Valentine.
