Harry/Snape
It was effective back in 1998 too. I'm sure you'll read it soon enough but Robbards was in charge of the Aurors, and Ron, Neville and I became their best Aurors a day after the battle. Robbard has been pushing me to become Head Auror for months now, but I'm not ready to give up the field.
I can lead people, and usually not to their death.
Can we make that into a list too? If you get to go whenever wherever, you know people will flip aka Sirius.
Voldemort summoned you to the Shack. He thought you were the owner of the Elder wand. You tried to explain that it wasn't true, but he ordered Nagini to kill you so he could get his wand (the idiot didn't even know that it doesn't work like this). I was there. You saw me and while you were dying, you released a cloud of memories. I was able to put them in the pensieve and saw what you had done, starting with your friendship with my mother, when you told Dumbledore about the prophecy and the hex on Dumbledore.
