Can I keep a leased car until my bankruptcy discharges even if the primary signer's discharge happens first?

I am a co-signer on a leased vehicle. The primary signer recently filed bankruptcy and I told him not to reaffirm the lease since I got a terrible deal but had no choice at the time. His discharge is coming up this month. I on the other am going to file before his discharge happens. Will I be able to keep the car until my discharge happens or will they take it when his discharge happens? Will they take the car if I don't make payments on it during the bankruptcy process?
