@propertyofdangervest This may sound really dumb, but please hear me out.
What if, for your one shot book (Love Conquers all, Book 2.5) you could come up with a chapter of a still young RJ, going on an adventure with Lucy?
We never did get to see Emmet or Lucy together much with their nephew, I'd think it'd be really cool to see RJ bond with his tough, edgy Aunt Lucy.
Maybe going to stop some evil power together, and they're the only two still able to stop it, such as Rex, Marie, Emmet, Faith, Watevra, and all the others being captured or something?
And maybe, they could even have a little talk about how Rex became himself, and RJ asks Lucy why she thinks her alternate self didn't go back for Rex, but her real self went back for her Emmet?
Just an idea. I hope you may take it into consideration, but it's cool if you don't. I really love your Books, and can't wait for more of your incredible stories!
