Leareth goes to his room and stares out the window some more.
He keeps feeling upset, which is confusing and frustrating, and normal he would decide it was unhelpful and try to dissolve it, but - it's not like he needs to be at maximum effectiveness right now. He - maybe doesn't need to be ever again.
Has he ever, in his life, had a retirement plan?
He expected to win. Someday, eventually, because he knew he wasn't ever going to just give up, and he could see paths to it, even though they were very hard to follow, with awful costs. He knew the time would come when he was finished. What was he expecting?
Leareth hadn't expected to feel so deeply sad, and tired, and - lonely?
And the dull sense that so much of his life was pointless, in the end. Choices he'd deemed worth it in expectation, at the time, but - he's not trying to predict the future, anymore, the future is here. And there are so many detours along the path he took - no, don't hide between that, so many people he murdered and harmed and mind-controlled - and none of that mattered. All that mattered, in the end, was that he could offer Tarinda resources and invent a novel form of Gate.
...some part of him wonders, quietly, if someone shaped like him even fits into Sing's world. What is he, what is a Leareth, except for someone who will work relentlessly no matter the cost until everything is fixed? Now what?
