 Wounded, the Psiren disappears, and uses illusions to separate Kryten and put him in the waste compactor, whereupon it proceeds to attack Lister and Cat, after Rimmer's light bee runs out of energy.Kryten, surviving the compactor, manages to kill the Psiren by crushing it with his now cubed-shaped body, allowing the crew to recover and continue pursuing "Red Dwarf".This episode features the first appearance of Kochanski since series 2's "Stasis Leak", albeit as a Psiren illusion used to fool Lister.
