The Caretaker Quest - Part 4

This is part 4 of the "side quest" for "Disappearing Hogwarts".
An unofficial alternate timeline based on HeadQM´s highly praised quest, Disappearing Hogwarts.
Reading the original story is not exactly necessary but heavily encouraged.
Created mostly as a place to wait while HeadQM was away for a while but slowly evolved into his own thing.

Quick recap so far:
Recently graduated Ravenclaw student is hired at Hogwarts as the new Caretaker.
Something dangerous and mysterious is happening.
Harry Potter is the new Headmaster of Hogwarts and extremely stressed.
Somehow, you can see ancient magic.
Peeves ripped out your foot.
Merlin himself is stuck in your head and slowly recovering his memories.
Potter’s daughter also had a powerful wizard inside her head.
Tactically used your enormous penis to somehow turn said wizard into a metaphorical vegetable by erasing his mind.
You have a sportsy German girlfriend.
And you are now in a coma and she is the new MC for a bit.
What will happen now? Let's find out!
