où il allait
Nobody knew where he was going.
Personne ne savait où il allait.
— The Needle (1989)
He took off at full speed without saying where he was going.
Il est parti à toute vitesse sans dire où il allait.
Did he say where he was going?
A-t-il dit où il allait ?
— The Chaser (2008)
I wonder where he was going.
Je me demande où il allait.
— Amarcord (1973)
I asked him where he was going.
Je lui ai demandé où il allait.
