My Hero - Season 5 - Eps 4: Cassie Come Home
Janet's mother Ella becomes a trainee JP. When visiting Janet and George she comments on the fact that Ollie hasn't spoken a single word yet. He responds by talking a language that sounds like baby talk (George has been teaching Ollie the language of Jupiter). With Ella's thoughts in mind, George goes out to get some educational stuff for the kids, he ends up getting porn for them and giving Ollie a cigar and alcohol. Ella takes Ollie and Cassie away from Janet and George but without them Cassie reverts to being a normal human.

Synopsis
My Hero is a BBC sitcom created by Paul Mendelson. The programme ran for six series, first broadcast in February 2000, and concluding in September 2006. The series follows the antics of the dim-witted superhero "Thermoman", portrayed by Ardal O'Hanlon in series one to five and by James Dreyfus in the final series. The series was regularly directed by John Stroud. In the UK, the digital channel Gold regularly re-runs the programme, although the last series has yet to appear on the channel. In the United States it was shown on PBS and, briefly, BBC America. In Australia, UKTV offered re-runs of the first three series, while BBC Entertainment provided repeats for Scandinavia.
