Supergirl's arc: how would u write it?

For me, guess imma give her the Zuko treatment, maybe? Start off as an antagonist or rather, manipulated/misguided etc. A major enemy of the heroes, then eventually, she'll slowly realize the truth, and her arc in s5, if not... s6, likely ends like zuko's in book 2, she eventually gets conflicted whether to still follow darkseid or defect to the heroes' side, but granny likely toys with her mind/spins the tale that she chooses to betray the team. Then eventually, say she was commended for choosing loyalty, and once alone, she was like "what have I done?" Then next season is the part where she'll slowly turn against apokolips and join the team? Like I said, similar Zuko arc perhaps
