[ Aether sees him coming, and while he can't exactly remember having any experience again a person with dual weapons... it seems he has muscle memory that serves him very well.
He doesn't try to clash with the other's weapons, choosing to sidestep and pivot, using his sword to deflect steel in case may have miscalculated his dodge on. Their blades shouldn't touch if he's successful though, and he'll shift his arm to swing the sword out horizontally from its original guard position to attempt and graze Childe's side with it, all the while careful not to leave his own side, closest to the other's front, wide open to an opportunity of being gutted in the process. ]
