'They're my cousins? They're all my cousins?'

'Yes.'

'But there are so many! I'll never be able to tell them apart!'

Irissë smiled patiently. 'It gets easier with time, although I don't think anyone will ever be able to tell Ambarussa apart. Come on, they don't bite.'

As soon as they approached, one of the dark-haired brothers (Tyelkormo, perhaps? She was sure that she would never learn all the names) and swept them a graceful bow, although his dignity was ruined by a broad grin. 'Irissë, welcome as always! But who is this lovely young lady?'

'Artanis,' she said shyly, and watched as Tyelko's smile was reflected across six faces, while another appeared briefly on the face of Fëanor, who stood not far away.

Notes: Tolkien owns everything, and Young!Nervous!Galadriel had to be written to be believed. Since this is set in Valinor, I've used their Quenya names, so Irissë is Aredhel, Ambarussa is both Amrod and Amras, Tyelkormo is Celegorm, and Artanis is of course Galadriel. I do admit to being curious about the possibility of Aredhel/Celegorm - it might have saved a lot of trouble.
