Lacrimosa in the Tesco Coffee Aisle (слэш)

Lacrimosa dies illa.
Qua resurget ex favilla
Judicandus homo reus.
Huic ergo parce, Deus.
Mournful that day.
When from the ashes shall rise
a guilty man to be judged.
Lord, have mercy on him.
From the Lacrimosa, part of the Dies Irae sequence in the Requiem mass.
Snape returns from the dead and, as always, battles with his conscience. Meanwhile, Harry takes his son shopping, encounters regrets of his own, meets an elf who is too clever by half, discovers how to get up Lucius Malfoy's nose and is forced to choose between his wife and a fantasy from the deepest, darkest part of his soul.
