The only mistake was Blake not giving them warning about Adam beforehand and Miles being a fucking moron in the Livestream saying that she "learned her lesson". She acted in the only manner she could to save someone she cares about as fast as she could because as far as she knew he was going to kill her right then and there. She had no time to do anything else. She couldn't shoot because that'd hurt Blake as Yang's only ammo has been shown to be spreadshot or explosive rounds. And Blake's aura wouldn't protect her as it was already weakened to the point Adam could stand her. So she did the only thing she could to get the threat away from Blake as fast as possible. That's not a mistake, that's a shit situation. There's a difference and it's stupid as fuck people don't get it.



Miles' comment is stupid as fuck, because the only lesson to be learned there is to never try and save anyone again. But he's clearly never been in a life or death situation, so his ignorance is somewhat understandable. Or would be if he wasn't a writer.
