She was exhausted. As much as she just wanted to go sleep in Jack and Robby's guest room, to curl up between them on the couch, she knew they would have questions she couldn't answer.

Summary
"He knew this wouldn’t work, but he needed it to work this time. More than when he was in Nebraska, more than when he was homeless, because otherwise Trinity and his friends and Jack and Robby would know. They would find him in this cold, dark room and realize how weak he was."

Summary
In theory, Robby could be perfectly happy with it being just the two of them for the rest of their lives, but deep down, he would always imagine they could be more fulfilled. He tries not to insert his mate into his domestic fantasies because it only makes the loss hurt more. Jack would be a fantastic dad, likely better than Robby.
It was all speculation and daydreaming until one day it became real. Last week, they received life-altering news. The system had a vampire-wolf hybrid in need of a home.
A twelve-year-old boy named Dennis.

Summary
Dennis has a problem. He's surrounded by incredibly attractive, highly competent people. Why does everyone in the ED have to be so darn good at everything? Especially his married attendings?
If they had kinks back in Nebraska, nobody told the preacher's kid about them. Dennis is a late bloomer but lucky for him, his roommate Trinity is there.
A story of awakening, set around Season 2.
