Magic Fire - S2-E13
Character mistake: Bosley and the Angels are in the office and they discuss the case they have just solved. Bosley calls Charlie "Charles", which despite being correct is definitely odd. Nobody has ever called Charlie by his given name. (00:45:50)
Answer: After going through a number of cast changes that failed to improve the show's slumping ratings, Tanya Roberts' character was added as "street-wise" former model. This was probably an effort to give a different and edgier character dimension to the show.
