Arthur holds a banquet for The Doctor, Leela and the knights as an attempt to smooth tensions but the Doctor talks about nothing but over-riding the block and not having any contact with any other Time-Lords.
Leela snaps and berates the Doctor for being so obsessed and ignoring her. She tearfully asks Arthur if he can use his TARDIS to take her back to 1985. Arthur says he can't because that would drain too much power and take the field generator offline leaving them visible to attack. Leela storms off and the banquet comes to an end.
Later that evening the Doctor is in his bedchamber when Guinevere enters. She tells him that he is being selfish. The Doctor replies that he must do something to make up for what damage he did as a CID member.
Guinevere says:
It's not me you have to tell. It's Leela.
The following morning after a restless night the Doctor goes to Leela's bedchamber and apologises profusely for letting her down. Leela is unsympathetic and says she knows Guinevere has spoken to him.
The Doctor says:
"Throughout all my lives, all my regenerations I've known what is right. I've incurred the wrath of so many people, so many races, destroyed so much and left so many dead because I knew what I was doing was right. And now I know that that sense of right, that sense of justice was my attempt to salve my own conscience because of what my own people, my OWN PEOPLE did to me. Daleks, Cybermen, Sonatarans. They still in the nursery compared to the Time-Lords. Billions of years, that's what it takes to become truly evil.
I never settled down, never knew what it was like to be truly happy. The Doctor, the wonderful Time-Lord. I've lost everything I ever cared for. I've pushed so many people away. Susan, Jo, Sarah-Jane. Lethbridge-Stewart once called be a pompous old fool and he was right because I had this mindset that I was right about everything.
That's not true. Ive been wrong about many things, made so many mistakes and lost so many good people and now its happening again. Leela I am so, so sorry"
The Doctor bursts into tears and runs out of the bedchamber followed by Leela. He races towards his TARDIS....
