The underlying fear for his condition adds depth, reflecting the emotional complexity as the woman navigates her role as a supporter.

Why is this sentence supposed to be here? Maybe it's kind of a manifestation of emotional collapse? I am not sure...

We can observe the sarcasm in the sentence which comes from the contrast between Isabel's concern for Kaden and the seemingly trivial nature of the situation she describes—accidentally locking him inside with the keys. On the surface, she reflects on her responsibility as a mother and the anxiety of leaving a child alone, which is a serious concern. However, the way she phrases "unless you count the time she accidentally locked him inside with all the keys" implies a level of absurdity and a flippant attitude towards a situation that could be viewed as neglectful or careless.

the conversation encapsulates a turning point in the narrative, where hope begins to wane and the reality of their situation settles in. It serves to heighten the emotional stakes, portraying the mixed feelings of fear, grief, and a desperate hope for rescue, while also emphasizing their individual struggles as they navigate a terrifying situation.

Bookend the emotional turmoil and urgency that Isabel experiences regarding her child, while also framing the impending threat of danger.
