Susan Beth pointed out the practical reasoning that might be behind Blake's eye injury... but it was *still* on the same side of the face as Travis's.
This is one of those instances where intent is possible, plausible, but also explainable by other means (once you have it to an eye injury, the chances are 50-50, and if it had BEEN the other eye, the fans would talk about 'mirror images' and how Travis was blind to good and maybe Blake has gotten a bit blind to evil in individuals).
