He said that the PK had killed most of his people and that he was a member of a slave race (sorry, did not catch the name). The glowing part of his face was not fully explained, but something about it allows him to cloud his thoughts, hide his emotions, and conceal information from the Aurora chair. When John was trying to recover from the chair and was getting a little hysterical the-guy-with-the-mask (sorry again - really bad with names!) took his mask off and the light from that side of his face seemed to affect John psychically: calm him down, and relieve some of the mental suffering caused by the chair.

: Does ANYONE know who the father of moya's baby boy is? I missed it

In one of the early episodes the crew were scouring Moya to find any leftover PK devices and remove them. D'Argo was in an access shaft and found a round shild with PK symbols pluggin up what looked to me like another passageway. D'Argo kicked it loose to remove it and when it came away it released a shower of tiny particles. The crew later realized that these particle were a catalyst for pregnancy.

Now that we know that Moya's baby is not a normal leviathan, I would guess that the PK tried to bioengineer a leviathan warship. How well it worked we will have to wait and see.
I wonder, as Rygel mentioned, who will have more influence on the baby - Moya, or whatever PK programming is left over.
