Kimber's bonds with other characters on the show are very telling. Although she is Jerrica's sister, and occasionally has a burst of sisterly loyalty, I think that Jerrica's way of playing the mother figure rankles on Kimber's nerves and causes something of a rift between them, just beneath the surface. Kimber treats Aja far more like a big sister figure and I've come to believe that it is Aja she is closest to of all of them. Aja too seems to reciprocate the bond - in 'Culture Clash' it's Aja who corrects Kimber's atlantic/pacific mistake, in Island of Deception they are sitting together in the lifeboat and there are many times when Aja and Kimber team up, particularly in later episodes. I think that, though they clearly have their disagreements (Dear Diary video, start of Bands Break Up) there is a good relationship between them.
I don't think that Kimber is particularly fond of Video - she pays little attention to her when she is there, and is sulky towards her whole father's day video idea - perhaps resentful at the idea even being brought up, since it's clear her father meant a lot to her and the wound is still fresh. This is another example of Jerrica's lack of comprehension where Kimber is concerned. However Kimber has a good heart, for she goes to comfort Jerrica straight away in 'Out Of The Past', when Jerrica is remembering their mother's death.
Kimber's relationship with Shana and Raya is pretty amiable. She is clearly friendly with both girls - she and Raya gossip about Shawn in Scandal and Kimber is upset to the point of tears when Shana leaves the band in Talent Search.
Where the Misfits are concerned, aside from Stormer, Kimber has little love for them, though I do wonder sometimes if she's secretly envious of all that they do. Since she's under Jerrica's thumb sometimes I wonder if maybe she'd like to be a Misfit for a day just to be able to get her own way and act out without being suppressed. Again, though, her perception of the Misfits is generally two-dimensional and only at surface level, she doesn't want to dig deeper. She has an ongoing rivalry with Pizzazz over men - this starts with Shawn Harrison in The World Hunger Shindig, but continues with Steve in Hot Time In Hawaii, Shawn again in Scandal and in the video for Top of the Charts Pizzazz alludes to Kimber always getting the breaks. However, despite this rivalry Kimber proves once again that despite it all she's a softie at heart by wanting to help Mr Gabor make up with his daughter and understanding all too well (for once) the problems of Pizzazz's childhood. In a way it was a shame this wasn't expanded upon, since maybe Kimber could have done some real good for Pizzazz that way. Headstrong and impulsive she may be, but you always get the feeling that Kimber would be only too glad to stick around if anyone should happen to need a hug :)
