Well, it depends on which specific comic series you're referring to. In some, Agatha was a prominent character, while in others, she might have had only a cameo or no appearance at all.
Agatha Christie was a famous British detective novelist known as the "father of detective novels." His works were mainly detective novels, and his most famous works included Murder on the Oriental Express, The Massacre on the Nile River, Sin Under the Sun, and so on.
Agatha Christie's works often involved various elements such as murder, detective, password, murder methods, etc. Her plot was compact and logically rigorous, which was very popular among readers. Her works have been adapted into movies, TV series, stage plays, etc., and have a wide readership and high ratings around the world.
Agatha Christie's works were unique, full of suspense and uncertainty. The readers often kept guessing and reasoning until the truth surfaced.

One idea could be that Norman and Aggie team up to solve a new mystery in Blithe Hollow. Maybe there are strange disappearances that only their combined abilities can figure out. Another plot could be Aggie wants to experience modern life and Norman has to show her around, leading to some comical and heartwarming situations. And they could also face a new supernatural threat that is more powerful than the ones they've encountered before, forcing them to rely on each other more than ever.
Their relationship can be developed by having them share more personal stories. For example, Norman can tell Aggie about his insecurities and Aggie can share her memories from when she was alive. This will make them understand each other better.
