As the line of reflection can the second child know everything that's happened so it doesn't need to be told twice

It seems like you're asking about the concept of reflection in terms of communication or knowledge transfer, possibly in a metaphorical or philosophical sense. However, the question is a bit unclear. Here's a general interpretation:

If we consider the "line of reflection" as a metaphor for communication or knowledge transfer, and the "second child" as a metaphor for a person or entity receiving information, then the question could be interpreted as asking whether the second person can fully understand or know everything that has happened without needing the information to be repeated.

1. The first step is to ensure that the initial information or event is clearly and accurately communicated or demonstrated to the "second child". This could involve verbal communication, written communication, or direct observation.

2. The second step is for the "second child" to process and understand the information or event. This could involve asking questions, seeking clarification, or reflecting on the information or event.

3. The third step is for the "second child" to demonstrate their understanding or knowledge. This could involve explaining the information or event back to the original source, applying the knowledge in a practical way, or making decisions based on the knowledge.

4. If the "second child" can successfully demonstrate their understanding or knowledge, then it could be said that they "know everything that's happened" and the information or event doesn't need to be "told twice".

However, it's important to note that this is a simplified interpretation and the actual process can be much more complex, depending on the nature of the information or event and the individual's ability to process and understand information.
