The Troublesome Thing About Time (гет)

Hermione was sick of adventure. She'd had her fair share, and taking a seat at the desk in the back of the DLME was all she could have dreamed of -- until it wasn't.
One day Hermione is summoned to the bowels of the Ministry where she is met by the lead Unspeakable who has a rather odd situation that needs to be dealt with.
Draco Malfoy has just arrived from twenty years in the future and insists on speaking to his wife, Hermione Granger.
The only problem is that the Draco Malfoy she knows is still the snarky, button-pushing boy upstairs--and not the man in front of her now.
