Assassin8 has accessed the Carrier, taken out the rest of the Authority and is ready to destroy it and everyone on board. The only thing standing between him and complete victory is the Midnighter.

While Assassin8 sweeps everybody in the Carrier, Midnighter is waiting back in Harmony, and the waiting pays off, since in order to scape the Carrier, Assassin8 must go out the way he came in, meaning, in the hands of Midnighter, that subdue the creep and make nasty things to him and the contractor...Midnigher beeing himself, not "Lucas Trent", the persona Jenny tried to input in him. A nice finale.
