Nelly is working for a big company. She is kidnapped. The kidnappers asked a huge ransom. Olivier is her boss and boyfriend. "Old man" is the company chair.
"Olivier knew the company wouldn’t pay a huge ransom. Not even the old man could convince his board to approve such a transaction. He was expendable. Nelly was even more so."
I do not understand who is expandable (Olivier or the old man) and what does expandable mean.
Thank you for your help.
