In which episode does Kryech promise Skinner a cure for a fatal illness, only if Skinner would make positive that Scully's baby isn't born?

I remember, the scene in my mind, but yet I can't come to a title. I also, remember that Kryech didn't want Scully's baby to be born because it would mean the end to all humanity. ( Baby suppose to lead the alien race) Plus, the super soldiers are afraid of the baby because he's 더 많이 advanced. The baby was born a super soldier, others had to be experimented on to be one. Hopefully, this information helps!! I would 사랑 to watch it!! LOL...
