Turns and departs (4)
I believe the answer is:
goes
I believe this clue is a double definition.
'turns' is the first definition.
(I know this)
'departs' is the second definition.
(I know this)
'and' acts as a link.
(Other definitions for goes that I've seen before include "Travels; attempts" , "Disappears; runs" , "Leaves; operates" , "Works" , "Moves" .)
