This is something Scott had done before. In X-Factor #68 He and the team (the origional 5 X-men) are on the moon with the Inhumans fighting Apocalypse & the Dark Riders because Ol' Pocy had infected Scott's son Nathan Christopher with the trans-mode virus. He had only moments before been told the only way to save his son was to give him up by letting Askani take the child to the far future. To defeat Apocalypse Cyclops with his powers boosted by his dying son and his own unyielding grief lets rip the mother of all optic blasts. I say this moment was much sweeter because it wasn't just anger. It was grief, hurt and the fear that even if Nathan lived he would still never see the boy ever again. The art was better as well.
