Nadav is tired, frustrated and haunted, yet he smiles when we meet. For 690 days, he has been waiting for the world to change, and he's still waiting, and hoping.
Back on 7 October 2023, his father Tal was seized by Hamas and taken to Gaza . Tal is now dead - it's not clear when he died, but the simple, brutal fact of his death is not in doubt.
What is unknown - indeed, what cannot be known - is when Tal's body will be returned to Israel .
"My dad is still being held captive, although he is not alive. My life is stuck," Nadav tells me. "In order to continue living and start the healing process, we need them home and we need the war to be over."
