His natal Saturn is pretty bright, and in the third house it’s well protected and encouraged with all his planets from Aquarius. I’d say this transit made him also much more structured, smarter and a better communicator. He also channels well the saturnian energies into his work (6th house ruled by Saturn). I don’t see any problems with Saturn. If you are in his proximity in daily bases, maybe you’re witnessing the Neptune conjunct natal Sun making him either choose his partners according to how spiritual they are, or being unrealistic in his expectations from his partners. Good luck!
