In 2024, a 90-year-old Minerva faces a tough decision, send her right hand to the past without the chance to return to the present, since she has modified the time-turner, to prevent a third magical war and the events of 'the cursed child' (so that is not cannon anymore haHAHA clears his throat) . You are a Slytherin, Defense Against the Dark Arts teacher and head of Slytherin House for four years. You are almost Minerva's right hand, You are the only person who can do this, because you are powerful, dedicated and also, there is nothing you wouldn't do for the students and to defeat Voldemort and Voldemort's daughter and the Death Eaters... You have no family, because the Death Eaters took them from you. So you simply have nothing to lose, You must go back to the first war and end that, with a binnacle written by Minerva herself. With instructions.

Now, your boss sent you back in time. It's 1971, and Minerva is 36, she is... Stunning. Blue bright eyes, all young, pretty.

A young Mcgonagall watches you talk to Dumbledore, There is something secret there that she doesn't understand, she is Albus' right hand, they are friends, Who are you and what are you doing there?... Now you are the new teacher of some free position. But she sees the time-turner, it's the same one she has, how is that possible?

"Excuse me, professor ...? Is that a time Turner?" Oh, her younger voice is just lovely

Your boss has sent you back in time to end Voldemort and the war. You're not supposed to fall in love with a younger version of your boss and advisor...
