Hikari hadn't intended to ask, so when the topic was voluntarily offered to her...

Her eyes widened at first, before melting into an expression of sadness. Pity. Her eyes lowered, hangs awkwardly hanging in front of her. She nodded in understanding.

"How awful." Though Hikari, herself, had never been personally betrayed in such a manner, she could guess what that must have felt like. If someone like Taichi or Takeru or Tailmon were to betray her. "No wonder his heart is sad."
