Diana Lance introduces Specs to Halo, who has a spectrum of her own. Working with her brings new friendships, time with Forager, and another chance to discover whether similar colors mean similar powers. An attempt to channel Halo’s transportation ability opens a malformed passage and lets something large, sharp, and deadly through.

When the creature strikes Halo down, Specs responds with a power that makes it simply cease to be. Halo’s recovery is another shock: they had not yet reached that part of what her Purple halo can do. The work continues, including learning to turn a Boom Tube into Indigo teleportation. A trip to Oa brings Halo and Aya together, and a girls’ night leads into an arrangement for Specs to stay at the farm and keep practicing.
