What happens if I download something while on a vpn, can I access it when im offline?

So here’s the deal I have a vpn that works well for me (cyberghost) and I wanna watch a show that is only available in germany.

Now I am not in germany (obviously) I am going on a trip where I will only have a bit of cellular data so this is what I wanna know.

A) Can I download something now using my vpn and watch it later if netflix realizes im not in germany because they will see my ip thanks to my cellular data?

Maybe I could connect to vpn using the tiny bit of data I have and tell netflix im in germany and watch it from my downloads.

B) will this work

Also if I go on the vpn now, download the show, turn off the vpn and go on netflix.

C) will I be able to watch it?

D) what if I go on with vpn, download show, go back without vpn and show is not visible. Go back to netflix with vpn, will show be visible again or will it be deleted from when I went in without vpn?
