The Year of Star Trek ends with a promising ‘Prodigy’ finale
"Supernova, Part 2" spends its first act quickly resolving the cliffhanger set up in part one before then moving into full coda/wrapup/setup mode for its second and third acts. This is definitely to the episode’s benefit, because in the process it ends up being the best and most satisfying episode of the season — not to mention demonstrating the most thematically resonant and relevant material that a kids’ Trek series of this type should be putting forward.
To make a short story shorter, the kids realize that to stop the weapon from destroying the entire fleet, they have to destroy the Protostar by destabilizing the engine core (resulting in the titular supernova). This would wipe out the entire star system and the present fleet, so they must move the ship far away at a fast enough speed to spread out the blast’s destruction and minimize it in any one location. This is the precise level of technobabble that a story like this needs — sensible and straightforward while making it about the characters’ choices.
