Girl meets boy — and ducks (6)
I believe the answer is:
evades
'ducks' is the definition.
('evade' can be a synonym of 'duck')
'girl meets boy' is the wordplay.
'girl' becomes 'eva' (girl's name).
'meets' means one lot of letters go next to another.
'boy' becomes 'des' (short for Desmond).
'eva'+'des'='EVADES'
'and' is the link.
(Other definitions for evades that I've seen before include "Escapes, avoids" , "Dodges or equivocates" , "Dodges, say capture" , "Avoids by cleverness, maybe arrest" , "Shakes off" .)
