Well his father is Black Manta, he probably just want revenge for death of Tula and his father tell him how could do it or maybe he turned bad to spy on The Light

I think that Artemis, Red Arrow and Kid Flash maybe have their own episode like in season 1. So they can show whatis happen to them and dont waste a episode doing flashback and continue to explain the plot.
