Summary
The Source breaks an age-old agreement between good and evil by stealing The Hollow, an ancient vapor which he uses to absorb Piper & Paige's powers.

Notes and Trivia
thumb|300px|right|Charmed and Dangerous WB Trailer
 * The title is a reference to the phrase "armed and dangerous" which is used by police when pursuing a suspect with some kind of weapon (armed) and has the intent or ability to cause harm (dangerous).
 * This is one of the nine episodes with the series title, "Charmed", in it.
 * Piper loses her powers for the ninth time.
 * Paige loses her powers for the first time.
 * This is the second time that Leo is shot with a darklighter's arrow, the first time being "Love Hurts". This time he is healed by Paige, who was channeling his own healing power.
 * This is the first appearance of Debbi Morgan as The Seer.
 * The Seer said she helped the Charmed Ones for her own future. This seems to be foreshadowing her intricate manipulation of Cole and Phoebe in future episodes in order to become The Source in "Womb Raider".
 * This is the first appearance of the Hollow on the show. It will appear again in Kill Billie Vol. 2 and Forever Charmed.
 * When the Source flames into the Halliwell Manor and attacks the sisters, he blows up the wall that Prue was thrown into, resulting in her death in All Hell Breaks Loose.
 * This is the second time that Pandora's box has been mentioned, it was already mentioned in "Sin Francisco". The box itself will appear in "Little Box of Horrors".
 * In this episode (and later in Desperate Housewitches) the Source is portrayed by Peter Woodward. Previously, he was played by Ben Guillory, and before that by Michael Bailey Smith (All Hell Breaks Loose).
 * When Cole comes in at the end of the episode to stop the Source, he runs in shimmering similarly to the way Leo orbed in the season 2 episode Murphy's Luck.
 * This is the second time Paige casts the Vanishing Spell.
 * At the beginning of the episode Piper says "Short of a darklighter, you win most likely to survive", and one shows up to kill him.
 * The Seer claims the Source went "into the void", she is making reference to the void left by Cole's demonic half being stripped of its powers.
 * This episode scored 4.7 million viewers and is tied with All Hell Breaks Loose as the highest ranked episode of Charmed on TV.com. It currently holds a 9.6 rating.
 * This was the first of five times that the Source was vanquished.
 * Paige wears a cream-coloured leather jacket she will wear again in "The Fifth Halliwheel" and "A Witch In Time".
 * Originally there were more scenes. The scene where Piper was writing her will was longer. It included a part where Leo asks what he is going to do with the Book of Shadows, Piper tells him to give it to one of his charges. There was also a scene where Phoebe and Cole are writing the spell to vanquish the Source.
 * This is the first time the Source shows his real face.
 * We find out in this episode that the Source lost half of his face in the battle which brought him to power. It was later mentioned, in an entry on Zankou, that it they fought each other for control over the Underworld.
 * In this episode when the Source was about to kill the Charmed Ones, the Source says "Say hello to Prue for me". In "Give Me a Sign", Prue says to Litvack before he was vanquished, "Say hello to the Source for me."
 * It was thought that the Source used Levitation to rise himself up after Phoebe kicked him over, However, the hand gestures that he used (placing his hands behind him and pointing directly them at the ground) and the fact that he possessed Telekinesis pointed to him using Telekinesis not Levitation. In fact the only time he was ever seen directly using Levitation was in one of Phoebe's premonitions after he stole her powers.(Brain Drain)

Glitches

 * When the Source unfreezes the vase he blew up a piece falls on the stand where the vase stood on. The piece disappears as the camera pans up.
 * When the Seer disappeard after helping the Charmed Ones, the camera is panned back to Cole (when he says "A very evil person"), some of the Seer's hair can be seen at the left side of the screen.
