What would of happened if Albus Potter had kept the time turner? What if the next generation kids had an 'accident' when Teddy Lupin was left in charge?
Will Teddy finally meet his parents? Will they get back in time for Christmas?

Teddy's POV. Takes place in the Christmas holidays just after the Cursed Child events have happened. The houses don't all match with the Cursed Child though.
This is my take on a Next Generation Time Travel story.
