Male of family that's kept in charge, after upsetting heir (5)


I believe the answer is:

'heir' is the definition.
(I've seen this before)

'male of family that's kept in charge after upsetting' is the wordplay.
'male of family' becomes 'son' (male child).
'that's kept' means one lot of letters goes inside another.
'in charge' becomes 'ic' (abbreviation for 'in charge').
'after upsetting' shows that the letters should be reversed in order.
'ic' back-to-front is 'ci'.
'son' enclosing 'ci' is 'SCION'.

(Other definitions for scion that I've seen before include "Young family member", "Offspring", "Offshoot", "Young child", "Plant shoot; descendant of a noble family;".)

I've seen this clue in The Times.
