Despite the final issue of the last panel suggesting Sam Alexander was blind, that’s actually far from the case (as he has his sight for he entire issue). What Sam is actually seeing (even when not wearing the helmet) is a series of dots that make up a map to the remains of other members of the Nova Squadron all of whom are dead (at least so far that we know).
After making the revelation, and serving out his sentence in Chess Club rather than detention for his latest fight with a bully whose behavior the principal so far has shown zero interest in altering, Nova eventually shoots back into the stars to investigate one of the small blips on the map where he not only finds the body of a Nova but the space-spider creatures who killed him.
Despite immediately abandoning the set-up of a blind Sam, the issue has fun moments on both Earth (involving Sam babysitting his little sister) and in space (where they hero discovers the fate of another Nova). Worth a look.
