Well, to answer my own question, I went to the back alley, lured out the creature, found an adult version, did a transform, killed them on the battle stage, then went to the Dr and did the pregnancy test to clear any eggs. Then rested and went back, a larva appeared, and then 'Johnny Cage' and his buddy showed up. I've attached my save file for anyone else. I suggest turning up the difficulty, otherwise it takes forever to lose to the larva. I hope this helps others.
