Yeah, the problem is that "having two variables" means something different than you think it means.

You can maximize for a function, that's fun and good.

I think a speculation is only a spoiler if you are a prophet.

My feeling is Torvald has to die, so that when Brienne bones Jamie, she's not making a choice. Choices are hard, it's nice when circumstances make them for you. Like how Ygritte had to die for Jon to bone Dany.
