okay THEORY. Could it be that Shuhanan already knew about Ro-Aren's death and has gone mad and shit and ofc misses her badly– so he wants to kill Estio to stop both of their hearts (since they share one heart?? if that was meant literally?) and so Shuhanan can join Ro-Aren in the afterlife?? Even if it means killing his own son??
damn the art style is making me forget how brutal their reality is
