Gunn waits to see how Rosalind's speech impacts the situation, but if she seems to be failing to persuade their enemies, he will attempt one last chance at bettering the odds before battle inevitably unfolds. Donning the Helm of the Undying Prince, and consciously aware of the risks, he reaches out telepathically to Melchizar in an attempt to subjugate the being to his will. He ignores the attempt to incite discord between himself and his dwarven counterpart--and Perseus, for his part, recognizes the attempt for what it is: a feeble attempt to sow disharmony between two beings who are joined at the soul.
