It's possible that they marry during the time skip, but she can s rank the others after it
But it would be weird if she only have Linhardt as an option
I don't remember it if it was confirmed not possible, sorry if that the case
Maybe, but then Edelgard can marry no male from her house beyond Linhardt. Prepare for some noise if that's the case.
Or she can marry only him before the time skip
Honestly I think that finally I'm going to start with Black Eagles... I 'm so in love with the new design of Edelgard.
And I also want to keep Dimitri and Claude for last.
