Came down after all others held back (10)
I believe the answer is:
restrained
'held back' is the definition.
('restrain' can be a synonym of 'hold back')
'came down after all others' is the wordplay.
'came down' becomes 'rained' (raining is a kind of coming down).
'after' says to put letters next to each other.
'all others' becomes 'rest' (as in the rest of a group).
'rained' after 'rest' is 'RESTRAINED'.
(Other definitions for restrained that I've seen before include "muted" , "Checked" , "subdued" , "Calm" , "Reserved, dispassionate" .)
