Arslan suddenly remembered his mother's words when she was fighting the group of people that blocked their path towards the River's residence. Aisha spoke to one of them as if they had already met before. Her words seemed to be knives for the enemy group leader but it was also clear how devastating that memory was for her.
Aisha spoke about her family being destroyed in the same way as the Crimsons just 20 years before them. Knowing this and hearing Elder Song talk about how Argo discovered the existence of the Red Moon Cult allowed Arslan to piece things together.
"Thunder..." Arslan said as he stared at Elder Song.
"What did you say...?" Elder Song widened his eyes. His face became pale.
"Aisha Thunder was my mother's full name." Arslan paid attention to the bewildered expression Elder Song had, 'He must know something about it!'
"The Thunder family?!" Elder Song loudly said, looking visibly nervous and shocked.
