Final answer:
The exact playful event that broke the tension between Lily and June is not specified in the provided text excerpts, but other examples from the texts show tension being resolved through personal connections.
Step-by-step explanation:
The playful event that broke the tension between Lily and June is not explicitly detailed in the excerpts provided.
However, there is a mention in one of the texts of a character named Lily where Louisa Ellis, feeling no unease when Lily Dyer walked past, suggests a potential moment of resolution or internal peace for Louisa.
If the playful event in question involves Lily from the references, it might imply a particular scene where the tension is resolved, likely through a tender or intimate interaction, as shown in the other excerpts where emotional tension is diffused through personal connections and realizations.
