It makes sense that she would, given she's chosen to join this one and not the others.

Because of her superior good taste.

And discerning wisdom.

Preen!

Smirk.

"She's very cute, isn't she," Domhildr stage-whispers to Celebrimbor. 

"In certain lights, perhaps."

- Tiny blush? 

"But I do see where you're coming from."

"Do I have to persuade you of this, too?"

"That might be helpful."

Thoughtful hum. 

Oh no.

'This could be a good thing, mistress.'

Nnnnnnnn.

' - I do not think Celebrimbor will react well to - flirting, when she doesn't know who I am,' she says, as a very very thin excuse to cover up the 'oh no' in her own head. 

'You could play hard to get for now. I think she might appreciate that.'

'...One idea...'

'Or you could continue to stammer and blush, not making any moves one way or the other. That has a different sort of appeal.'

'You're very rude, sometimes.'

Mental laughter. 'You created me to help you. I'm helping.'

'You're ganging up on me, is what you're doing.'

'But you like it.'

'...Yeah. I do.'

Satisfied hum.

She'll stick to 'lightly blushing and not meeting Celebrimbor's eyes as she conspicuously fails to engage with the teasing' for now, though.
