I’ve been thinking a lot lately about Will and immortality and characterization.
Why didn’t Will choose some extreme kind of immortality? He’s the type to self sacrifice so even if he didn’t want to be a vampire - he’d to it for Tessa. Once the children are grown why not? Why not just deed everything to Jamie and run away together?
It would be a scandal but the man married a warlock, he’s not particularly untouched by scandal. And unlike Jem and Alec who are committed to being Shadowhunters - Will is a Shadowhunter by circumstance more than choice. He joined them because his mother had always said they were heartless so he figured there would be no one there to love him. He’s got a hell of a hero complex but there isn’t any reason he wouldn’t be content to run off with Tess and be a vampire doing heroic things.
Yes there are vampire politics and expectations but the two of them have enough power to simply tell the vampires to fuck off and whoever they found to change him would have been made well aware of the plan.
Tessa would have taken some convincing but Will could have convinced her because it would have meant she didn’t lose him. They could go back and visit the kids and grandkids (who I imagine would not follow in those footsteps - they’d stay mortal and live out their mortal lives with their mortal families).
Will’s impulsive and committed. His priorities are the children, Tessa, Jem, first and everything else a distant second. Leaving the Clave couldn’t have hurt the kids once they were grown (though it would have when they were kids) and it would have meant he never had to leave Tessa and Jem. Will would make a crazy choice like that. To hell with sunrise, with the Clave, with everything else.
Will as a vampire who looks roughly 50, Tessa a warlock who looks roughly 20, running around the world getting into hijinks and trying to do good.
I like this plan.
