Tensions build as Tane and Leonella try to hide their relationship. Zandie, Degenhardt and Leonella lock themselves in the dorm, demanding to be allowed more of an equal say in how things are run on Star Runner. When Tane fails a flight test, Cyriax gives him an ultimatum; shape up or stand down.

Sheng manages to find a way to get the Star Runner back through the wormhole but it takes some skilled flying from Tane to actually do it. Zandie plays havoc with Tane's feelings for Leonella by suggesting she was Cyriax's spy. Tycho sees something out of the ship window. Have they brought something back from the wormhole?
