When D.J meets Steve's new girlfriend C.J, C.J is wearing the outfit D.J wore in the first season (blue cardigan and white striped shirt).
We meet Kimmy's younger brother, Jimmy Gibbler, who is never mentioned in the original series. It can also be assumed that Jimmy and Garth are the same person or that Kimmy has two brothers.
First appearance of Adam Hagenbuch as Jimmy Gibler
