I get out of the downpour with him (3)
I believe the answer is:
hal
'him' is the definition.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hal that I've seen before include "Prince -, Falstaff's companion (Henry IV, Pt I)" , "Henry (diminutive)" , "Shakespeare's prince" , "Shakespeare's Prince_with Falstaff" , "Falstaff's prince (H.IV)" .)
