Author here--thank you!! I'm so glad you enjoyed the fic even if it didn't seem like your cup of tea at first. :) I loved reading your questions! I think Booker would eventually tell her, but—in classic Booker fashion—I don't see him telling her until it's almost too late. Once he returns from exile, I picture the two of them cultivating a friendship that slowly turns into something more... And it's only when they're well on their way to having sex for the "first" time that he finally blurts out what happened. The guilt's been eating him up, but I don't think it would ruin things. I think he would expect it to, expects her to be furious and walk out, but considering just how well their first time went for Nile, I think she'd feel more relieved than betrayed. She never thought she'd have that perfect experience again, but here he is, and they can potentially spend eternity together.

Often I lean towards a sad ending, but with these two? I'm all about that fulfillment! :)
