Considering how many Kryptonian survivors are wandering around that was a fairly dense question.
Well Oliver could have taken her out with that shot instead he aims to wound I miss season one arrow he would have ended
I always found it funny that evil supergirl could’ve definitely heard Oliver say, “this arrow won’t” and then still let it hit her
Wait if they meant to stay at home wouldn’t the reverse flash have too stay with them since he is from earth 1

Oliver should’ve aimed for the heart. Also they never explain how he got a kryptonite arrow.
