Disturbs, distresses (6)
I believe the answer is:
upsets
I believe this clue is a double definition.
'disturbs' is the first definition.
('upset' can be a synonym of 'disturb')
'distresses' is the second definition.
(I've seen this before)
(Other definitions for upsets that I've seen before include "Unexpected results" , "Disapppointments" , "Disturbs or overturns (6)" , "Hassles" , "Disturbs or knocks over" .)
