Final answer:
The group stopped communicating after Henry's death because he was the glue that held them together, similar to historical instances where a central figure's loss complicated group unity.
Step-by-step explanation:
The reason for the group to stop talking to each other after Henry's death was due to his pivotal role in keeping the group unified. The various snippets provided from historical contexts illustrate similar situations where the loss of a central figure led to the dissolution or significant change within a group or community. For instance, following Muhammad's death, the early Muslim community immediately faced questions about leadership and the continuity of the community's unity. In the case of Henry, his death might have resulted in the group lacking a common purpose or the emotional bonds necessary to maintain their relationships.
