What I think will happen to the major houses in Game of Thrones season 7:
Cersei Lannister has secured her place as a queen, but it was the beginning of an end. Her recent political move literally made her the most hated ruler of Westeros. She has no support from the people and from any other houses in Westeros. Even House Tyrell, the Lannisters’ most formidable ally has already pledged its alliance to House Targaryen. House Frey? LOL. However, we shouldn’t underestimate Cersei. Not when she has lost all her children. I imagine Cersei will become very ‘evil queen’-like in the next season, killing everyone who approach King’s Landing with wildfires. We also have no idea to what extent Qyburn’s researches will help Cersei and her military might. We already knew The Mountain has became an undead thanks to him.
This will be interesting. While Jon Snow was declared King in the North, he lacks political skills which are essential to play the game of thrones. For now, the Lannisters, Ironborns (Euron Greyjoy), and White Walkers are not his primary enemy. He should worry more about Littlefinger. Sansa Stark, with her current political competence will help Jon dealing with this matter I assume. But Littlefinger should never be underestimated. Not when he can easily switch his alliance to Cersei Lannister. Now the most interesting part is the return of Bran Stark. He knew that Jon is not his own half-brother which made Jon’s entire legitimacy in the north invalid. Also, do not forget that Bran is the more legitimate heir to the Winterfell. Should Littlefinger grip his venom to Bran (and probably Sansa too), it will be very intriguing (I know, it will also be so unfortunate either). I am also curious about Arya Stark. Where will she take parts in here? Or will she just head straight to King’s Landing to finish her list?
Once, Daenerys was just a little girl given to Dothraki Khal as a piece of meat. Now, she is a a conqueror, a queen, loved by her people. Daenerys is an ideal portrait of a ruler. She possess all good qualities of a leader. Not to mention she has Tyrion Lannister, her most reliable advisor by her side. Now, more than ever, she probably has the largest army than any houses since she conquered the entire Essos and cemented the alliance to Tyrells and Martells (hey, Varys should also get special mention too for this matter). And of course, her dragons. I nearly forgotten XD At a glance, things are going extremely well for house Targaryen. But tthere might be some twist. You know, something has been bothering me. There are many occurrences that hints Daenerys going mad. Her inner voices (in books), her advisors constantly reminding her, and her emotional streaks at times. I imagine that she will be the mad queen… Now I do not want this to happen. I love her, really. Her growth, her characters. But one thing that we should never forget is that Game of Thrones always kill the people that we love.
