Can't really explain more as you'll know the episode but I will fill the gaps (or attempt to!) READ AND REVIEW! Rated T just to be safe! LL99 is back!

This is my take on the sequel to SleepingSeeker's story 'What Makes a Father'. Yes I have permission to use her characters and to write this. This is the most dark and disturbing thing I have ever written in my life. If you do not like it do not read. Contains rape, abuse and violence. Rated M for a reason. THE REAL CHAPTER 20 WILL BE UP SOON! Not abandoned I promise!

'She recognized him immediately, the plastron, the shell, the freckles that dotted his face. She took another step, looking closer towards the creature. Dirt was covering his green skin, scrapes and bruises decorating his skin. Chains around both his wrist and ankles, connected to the wall. And the worst of all, the muzzle on his face. The baby blue eyes filled with so much fear.'
