Notes and Trivia
- The Source's 'dream world' almost mimics the real world, for example:
- Paige says, "Got milk? Oooh don't think so." Earlier in the episode, Paige forgot to buy milk.
- When Phoebe comes to help Piper out, she's eating a cookie, and says to Piper "Not your best." Again earlier in the episode, she was making cookies, and they obviously weren't her best.
- Afterwards, while Piper is yelling at Phoebe to release her from the strapped bed, Phoebe says "stop obsessing". Earlier in the episode, Phoebe tells Piper that she told her to warn her when she began to obsess over something.
- The Halliwell Hospital is the manor, devoid of antiques and collectibles, and is painted in aqua and beige, traditional colors for mental institutions. The stain glass windows, the wood stained door frames and moldings, however, have been left the way they were, because it would take too much time for the set crew to restore them back to the original for the next episode.
- A season 6 episode of "Buffy the Vampire Slayer", Normal Again, has a very similar plot where Buffy finds herself in a mental hospital, wondering which reality is real. As stated in an issue of Charmed Magazine, the reason for this is because the episode writer offered similar scripts to both shows, with Charmed using the idea first.
- The "Smallville" episode "Labyrinth" also features a similar plot.
- In this episode, Cole created the biggest Energy Ball seen in the series.
- The Source wanted Piper to cast the To Relinquish Our Powers spell. The sisters destroyed the page with this spell in "Wicca Envy" after Rex Buckland manipulated them into using it.
- Piper loses her powers for the eighth time in this episode.
- Phoebe loses her powers eight time.
- Paige loses her powers for the first time.
- This is the last episode of Ben Guillory as the Source of All Evil. He will be replaced by Peter Woodward in "Charmed and Dangerous" and "Desperate Housewitches".
- In this episode, Cole whistles to get the sisters attention. This is later used in "Malice in Wonderland", where Piper whistles to get the other two to listen when they keep obsessing.
- This is the second time Piper has been put into a coma. The first time was in "Awakened".
- This episode scored 4.8 million viewers and is the third-highest ranked Charmed episode on TV.com after "All Hell Breaks Loose" and "Charmed and Dangerous".
- The title is a reference to the "brain drain", the phenomenon of talented and educated people from one country going to another country for better conditions.
- Paige says, "What do you say we click our heels and get out of this crazy joint?", a reference to the 1939 film, "The Wizard of Oz".
- Phoebe shakes the nearly empty milk carton at Piper and says "got milk?", a reference to the famous advertising campaign. Phoebe also made a reference to this slogan in "The Fourth Sister".
- At the end Cole says to Phoebe "Ms. Halliwell are you trying to seduce me?", a reference to the famous phrase in "The Graduate" by Dustin Hoffman.
- When Piper was hit by car she is bleeding on the right side of her mouth, but when we see her with the Source, she is bleeding on the left side.
- Piper: I'm gonna be so happy when I vanquish your sorry ass.
- Piper: Of course that would mean we should stop going after all of his demons, which would be fine by me. It would stop all the constant attacks.
- Paige: Am I the only one who think she's bumped her head?
- Paige: Got milk? Oooh, don't think so.
- Piper: LEO! LEOO!
- Paige: Would you stop with the "Leo Leo" you're driving me crazier than I already am.
- Paige: Hurry up Looney Tunes. Get me outta here!
