Charles in Charge is a show about a college student who becomes a live-in helper for the Pembroke family, consisting of mom and dad, teenager Lily, middle schooler Douglas, and 10-year-old Jason. From the second season on to the last one, Charles switches families and stays with the Powells, as the Pembrokes are moving to Seattle. The reason for this is because Charles in Charge originally ran in 1984 for the first season and was cancelled. However, it was revived in syndication from 1987-1990 and on the first episode of the 2nd. season, it is explained that while Buddy and Charles were on a camping trip, Mr. Pembroke got transferred from his job in Pennslyvania to Seattle, Washington. Mrs. Pembroke and Jason both show up in the episode to explain things to Charles and to say goodbye. From then on, the Powells are the new family who have leased the house and they also maintain Charles' services. Charles now has to contend with Grandpa, Mom Powell, (Dad is away in the Navy), teenager Jamie, middle schooler Sarah, and 10-year-old Adam. The Pembrokes and Powells are definitely not totally the same but there are some similarities.
In any case, I have seen some of the first season as well as the later seasons and they are all good. Buddy is the best. He is so crazy and hilarious. He and Charles are such good friends and have great times, dating girls and keeping everything at the household under control. It's great. Charles in Charge rules!
