Nyssa: My father is dead, my homeworld has been destroyed, everything that I have known has gone and you stand there with your coolness and your arrogance. What gives you the right to do nothing!
Doctor: Anger is a powerful emotion Nyssa. Used correctly it can build used improperly it can destroy. Its arrogance that has led to Traken being destroyed and Tremas dead. I am so sorry for what has happened. But I know what can happen when anger and arrogance are misused. Ive seen it across time and space. And I'm not simply doing nothing as you say. I could have left you on Traken and let you die with everyone else.
Your father was a good friend of mine and I feel his loss almost as much as you do but blind rage isn't going to solve anything. I promise you now Nyssa I...we will find the Master and we will make sure he pays for everything he has done. But for that to happen I need you to trust me...
