What if Walder Frey forced an immediate marriage between Robb and Roslin?

Let’s say that after Catelyn and Walder negotiate the terms of House Frey joining Houses Stark and Tully in their war against the Lannisters, Walder insists that Robb marry Roslin immediately, leading to a wedding that happens a day or two after the initial agreement is made. Assuming Robb goes through with the marriage and Roslin becomes the new Lady Stark, how would this have affected the wider story, aside from the Red Wedding pretty much being averted since Walder would’ve already gotten what he wanted?

What’s your favorite single scene in GOT?

Rewatching for the umpteenth time and just watched my favorite single scene….when Arya “trains” with Brianne in Winterfell. I love it because it opens the eyes of those around her to how truly a BAMF Arya is, and the first time we truly get to see her sword skills.
What’s yours?

What characters did you think wouldn't survive until the end? (spoilers obviously)

I was convinced that Sansa would die pretty much every single episode after season 1.
