Number Five indicated he wanted to mediate, which was something Otto had wanted to do but had failed to accomplish.
But now that they were aboard Number Five's ship, he really had the qualification to mediate. However, Number Five's mediation was solely out of fellowship and bore no compulsory element, essentially meaning it was up to them whether to comply or not, he just had to say his piece.
