This brain map was constructed from fMRI scans of participants listening to fictional podcasts called "The Moth". The fact these words are all grouped together suggests a high level of `arousal` which may be related to an emotive part of the story's narrative. You may very well have deduced part of the story. "child" does seem like an outlier when you consider individual words but it's the overall context that's important. Your second example highlights many words that related to time. wife, husband, *afterwards*, *afterward*, aunt, *staying*, *months*, weeks, *slept*, *waited*, *month*, *leaving*, *leave*, *until*, pregnant, decided, *date*, hadn't, wife's, *stay* Being able to visualise general concepts like this is one of the main benefits of the brain map. Reading anything more into it is prone to error.
