When BacT obtains his Visa, he can travel directly to Germany, NOT having to be in France first.
This could get tricky if BacT is coming to Europe for first time. At border control the agent may ask you for ultimate destination and will also ask you for proof of travel document and staying i.e. hotel bookings. BacT won't be having any of that related to France.
Good luck to BacT but Nili is handling it in the most appropriate manner.
