On my play-through I chose Royland as my Sentinel. I also chose to show Ramsey my 'army' rather than diplomacy or bargaining. I met Ramsey at the gate and then he came into the house. After some conversation, Ramsey tried to take my sister so I stopped him then he stabbed me in the throat, Royland didn't try to fight Ramsey or his men. In the 'next episode' section at the end it showed Royland and the other guy arguing over who should be leader of the House now that I was dead. Probably very similar to if you didn't choose Royland (Telltale seems to give a false sense of 'choices' that effect the game in a big way, but in reality the choices don't really matter and I suspect that whatever you chose, the endings would be very similar...)
