After knowing that her husband is dead Catelyn was sad and with Jamie caught she still had hope to safely bring her daughters back. She wanted to exchange Jamie for her daughters and was about to write a letter to Rob.
I entered the main hall where Rodrick Cassel, Maester Luwin, and Catelyn were discussing. Seeing me enter Catelyn immediately asked how I knew what was happening in the capital so early before anyone. I replied, " I have my company spread all over Westeros they act as my eyes and ears and I have a faster means of communication." walking to a seat near them.
I said, " Also don't think of exchanging Jamie with your daughters. Sansa who is betrothed to Joffrey still naively thinks her father has really committed treason and has been humiliated by Joffrey publicly at every possible event. Arya has escaped from the castle and was last seen being taken by people of the Nightwatch and is heading North with them. Cersei and Tywin won't be stupid enough to send Sansa back without the Northern Houses bending their knee to the King."
Hearing me both Maester Luwin and Rodrick Cassel agreed with my words. Then Catelyn thought for some time and asked for my advice. I said, " As you would know I have married Lagertha of House Mormont and am currently its Lord. I also recently married another woman who is the True Queen of Westeros, Daenerys Targaryen which gives me the right to the Iron Throne. So if you support my wife to take back her right I will rescue Sansa and after conquering Westeros I will declare the North as the Independent Kingdom." everyone was shocked hearing my offer.
Before giving them time to think I continued, " Your son Rob has fallen for a woman for a healer Talisa Maegyr and has already become a couple. Soon news about this will reach Walder Frey and you will be betrayed by him as Tywin has already offered to make him Lord Paramount of Trident for his help. Roose Bolton is also in on this as he wants to replace House Stark as Lord Paramount of North. Theon whom you and Rob sent to Iron Islands has joined hands with them and is currently on his way here to sack Winterfell. Rob is surrounded by the Frey and Lannisters on both his back and front. Winterfell is vulnerable without any men to defend it from Theon-leading Iron-borns or Ramsey snow-leading the Boltons."
After a long silence, Catelyn said, " How can you help us and take Iron Throne? Even if you are Lord of Bear Island you don't have an army. Why should I trust your words? "
I replied, " Well valid question I currently have 20000 soldiers at Bear Island and 10000 soldiers with my Queen Daenerys. I have also brought 20000 soldiers camping near Winterfell they will be deployed to kill the Boltons and Freys and assist Rob to defeat Tywin Lannister. Also, don't forget I have a cure for your son. In a few days, Theon will arrive with the Iron borns. Think and tell me your answer you know where to find me." with that I walked out of the hall to my room.
