If we could only do this.... and some other outcome would happen. Not so much. Sisyphus pushed the rock up the hill over and over again....same thing was always going to happen. This episode suggests that we might have the ability to ( 20/20 hindsight) fix stuff that was bound to not work out. Sorry that the writers seem to have made "Katoby" kind of cliche, especially for those of us that have lived that reality. The Kate/Phillip story feels expedited, like- lets wrap things up with all this unpleasantness, even if it makes no sense.
