I’m just imagining all the ways a Gwenvid soulmate AU could go down.
With the clocks Gwen just thinks “Great, I’m going to meet my soulmate on the first day of work. Why can’t it be more romantic or whatever?”
While David is going “Oh my goodness! Today is going to be the best day of my life! First day of camp, I get to meet my new co-counselor, and I get to meet my soulmate!”
or the whole first words your soulmate says to you is on your wrist.
“What the fuck?” could be on David’s wrist, and he has to deal with that all his life.
“Please watch your language” is on Gwen’s wrist.
Or really, anything could work out in this sort of AU and it would be funny.
