'What are we going to do with them?' Ron whispered to Harry through the dark; then, even more quietly, 'Kill them? They'd kill us. They had a good go just now.'
Hermione shuddered and took a step backwards. Harry shook his head.
'We just need to wipe their memories,' said Harry. 'It's better like that, it'll throw them off the scent. If we kill them, it'd be obvious we were here.'
'You're the boss,' said Ron, sounding profoundly relieved. 'But I've never done a Memory Charm.'
'Nor have I,' said Hermione, 'but I know the theory.'
She took a deep, calming breath, then pointed her wand at Dolohov's forehead and said, 'Obliviate.'

EDIT: forgot to say! Two people to thank, firstly
for a tutorial type break down she did a while ago which inspired the colouring somewhat ([link]
) and to
for their beautiful, easy to use brushes which did the obliviate spell ([link]
