#that is a human as a rat as a cup
That was a long 12 years for Wormtail.
Can you imagine how differently their lives would’ve gone if Ron, in trying to transfigure Scabbers, had actually transfigured him back into a human?
Just take a moment to imagine McGonagall’s reaction if Peter Pettigrew had abruptly appeared in her classroom from Ronald Weasley’s rat.
Take a moment.Or if Ron had fucked it up a little worse and couldn’t get ‘Scabbers’ back and McGonagall had take him to disenchant him and next thing we know there’s a naked Peter Pettigrew sitting on McGonagall’s desk and the kids in that class learn six new swear words, a hex they will never dare to use, and a fear of Minerva McGonagall’s wrath that will be with them until the day they die.
Ten and twenty years later first years are being pulled aside and warned never mess around in Transfiguration seriously the last time a kid mucked something up in that class Professor McGonagall used two semi-legal hexes, took down a Death Eater and sabotaged the rise of the Dark Lord before Potter had time to get his wand out.
