Don't stop him

You know very well that the girl didn't deserve what comes to her. You spent enough time with Ritter to know what he is capable of and have no doubts that he will be rough. Everything good in you screams to stop him. But...

But cruel truth is that you need Ritter. He has necessary skills and, what is more important, he is controllable and loyal. Yes, you and Clara experienced a fair share of his nasty glances and chauvinistic remarks but he never went beyond that. Sure, he most likely got something from Dorothy but that wasn't enough to satiate his lust. What he does now may calm him down for a long time.

On the other hand, Cassie is unlikely to posses any useful skills, have no male strength, useless in possible combat situation, and will hate you forever for what you just did to her brother. No. You won't stop Ritter from committing a **** "What a monster I will become in few months?" You whisper a question to yourself as you resigned to a horrible decision.

You have decided to not stop Ritter.Now you need to decide what do while he is "busy" You can gather supplies, wait outside to not hear anything or go find them and ensure that Ritter won't hurt the girl to badly.
