According to reader Barbara, HarryNews
According to reader Barbara, Harry is mentioned in the next episode of 'Charmed' pleasently called "We're off the see the Wizard." Here's the excerpt from the script:
"...I came here to help you with Merlin.' The Wizard overhears this and is insulted to be compared to an overrated hack and asks if he is the only wizard they ever heard of. Paige: 'Does Harry Potter count?' The wizard groans in disgust."
The show airs on the 25th at 9:00 PM
