"Ow," you groan, your voice stiffled by the hardwood floor you had your body splat against.

A portal. You had just came out of a portal in the middle of the lounge room, right before the Batfamily was about to enjoy their Christmas dinner. And yet, you weren't all that surprised.

You were part of the Wayne Family, well, kinda. 5 years after the following events, you had been adopted by Bruce Wayne himself. It's a long story, but let's say—after a year of living with the Bats—it was a bit of a surprise when you suddenly teleported yourself into the past, then immediately back, and then immediately after figured out you had the power to travel through time. Uh huh, yup, and infront of every family member who were at the dinner gathering.

Luckily, your family was full of midnight vigilantes. After a bit of training and a bit of accidental trips through the timeline, you had somewhat mastered the power to basically time travel.

Now, it was Christmas Eve, and you were almost late for the Christmas Dinner at the manor. And when you figured out that the donut shop you were supposed to snag desserts for the dinner was closed, you thought that travelling just 5 minutes back into the past couldn't hurt.

And boy were you so wrong.

5 years. You travelled 5 years into the past. Falling face first onto wood floor is bad? Try doing that by falling out of a portal, in the living room of your house where all of your family members sat except that they don't remember you—and that they are all armed vigilantes at night.
