Snape and ...
Pausing only to summon a loaded warbelt, Snape Apparated into the Alley.
Into hell. Smoke, flames, blood, screaming, bodies. Mentally, it was all same old, same old. But physically, the adrenalin rush was as visceral as ever, energising, addictive.
A bubblehead charm for the fumes, a Protego Maximus and a Speculumagia, and he waded into the thick of the fray, wand blurring, free hand darting to his belt, flicking phials of assorted mayhem at masked figures.
