Average bat family story. Isla is younger than Damian. Everyone lives at the manor. Jasonahs a white streak. Isla is a FANTASTIC sniper. Terrifyingly so. She knows a sniper better than she knows herself. The grooves and notches more intimately than her own fingerprint. No one maybe on earth is a sniper as good as she. Shes silent and never really talks. Shes also raised and born in the league of assassins. Isla was the perfect assassin. Like Damian. Damian was brought to Bruce a few years before isla was. Isla was not Talia’s daughter but she was bred into the assasins by willing participants, not taken from childhood. She was perfect. All silence and stealth. Daggers and hands where Damian was swords and batarangs. Isla was shadows where Damian was intelligence. They knew each other but isla was often kept away. She picked up the ability of the sniper just based off her training, but the sniper is not her main.
