Runaway
Eureka is being treated by the rescued Vodarac priest, and Holland uses what he says to drive Renton and Eureka further apart. Meanwhile, Renton's guilt is too much when he realizes all the people he's killed while fighting in the Nirvash, being apart from Eureka, and being mistreated by the Gekko crew. Instead of talking to them and discuss about their behavior, he decides to leave the Gekko, realizing the mistake he has chosen.
