Abby Kayden

Mrs. Abby Kayden is R.J. and Mel's mother and co-owner of a corner store in North Valley, California with her husband.

The Kayden's store is under an apartment rented by the Fernandez (Hector and Kiki).

At one time in the story arc "Into the Comics", a heated argument ensued with her husband Ben. This argument was about getting a new truck for the store. Mr. Kayden wanted it, but Abby disapproves. The Kayden siblings (R.J. and Mel) overheard their arguing. Mel believes that the argument is nothing. R.J. is dismayed that Mel is so clueless about the argument and believes that Mel is wrapped in her own world and that she didn't see what was going on with their parents. During dinner time, R.J. and Mel finally reveal that they overheard them arguing. Both Abby and Ben told them that there is no divorce in the future and explained the real reason for the sudden argument as well as the true meaning of having an argument. Abby laughed when Mel told R.J. that she told him that their argument wasn't serious.
