T4

You were born in 1980. So how on earth are you in the 1940's? There was a magic accident that occurred whilst you were with the Slytherins of your time. One second you were in the late 1990's the next? 1940's. You had travelled back in time to the Tom Riddle era. Now, forced to pretend you are from their time and not from the future, you have to degrade yourself to their old slang and pretend you don't know anything about Voldemort or the future... While also having to deal with the past Voldemort himself. And he doesn't even know it.
