One possible narrative.  Not a spoiler because like Jon or Sergeant Schultz, I know nothing Daenerys orders Sansa and Starks arrested and brought to Kings Landing.  She also orders all Lords of the Houses to attend Kings Landing to bend a knee. Everybody including Briene, Gendry etc come for the final confrontation in the last episode.  Daenerys intends (to put to trial and) to execute (burn) Tyrion, Sansa, Arya, Bran (i.e. all Starks), any Lords who refuses to bend a knee, and any other
