 Kat in particular is traumatized by the loss of two ships, the "Adriatic" (which was being escorted by Hot Dog) and the "Carina" (which was being escorted by Kat herself).Kat is plunged into a deep state of depression from a combination of guilt about her false identity, the loss of the ships, and the physical and psychological stresses of flying through the cluster itself.In her depression, she steals a white radiation badge (out of Helo's locker) and uses it to replace her own black one.
