Harry Potter and the Heart of a Rat

.

.

Eyes mean a lot. Like a barometer. They tell you everything – who has a heart of stone, who would poke the toe of his boot in your ribs as soon as look at you, and who's afraid of you, the cowards …

– Mikhail Bulgakov, The Heart of a Dog

.


.

Summary:

There are many things a wizard or witch shouldn't do while ridiculously drunk or high: flying, apparition, spellcrafting, Quidditch, Quodpot, microsurgery, wand repair, transfiguration and magical oaths, just to name a few. But listening to one of your equally wasted friend's 'brilliant ideas' is another one of the things you just shouldn't do. Now he's been hurled into the past, is surrounded by enemies domestic and foreign, and stuck wearing the skin of a cowardly, traitorous rat bastard. Never fear, Wizarding World – Peter Pettigrew, Gilderoy Lockhart and Dolores Umbridge are here to save you all! Er, yay?
