He is taken in by a girl - who fluttered them? (6)

I believe the answer is:

lashes

I'm a little stuck... Click here to teach me more about this clue!

'fluttered them?' is the definition.
I can't judge whether this defines the answer.

'he is taken in by a girl' is the wordplay.
'is taken in by' indicates putting letters inside.
'a girl' becomes 'lass' (lass can informally mean a girl).
'he' going inside 'lass' is 'LASHES'.

'who' acts as a link.

Can you help me to learn more?

(Other definitions for lashes that I've seen before include "Eyeshades for punishments" , "Beats" , "Blows delivered with a whip" , "Binds" , "Strikes with a whip" .)

I've seen this clue in The Globe and Mail.
