A question best left to the air traffickers I guess, but you do know there are procedural separation standards, don't you, Dick?
The night VFR aircraft must be appropriately equipped and the pilot rated, so he or she will have at the very least a GNSS and therefore be able to report distance and bearing from the airfield. The airliner will know exactly where it is with heaps more gear and likewise report its position. Based on that, the controller will no doubt ensure they are not near one another's position without appropriate height separation.
It was a trick question, right?
