*bump*Would also like to learn about the conjunction.
Maybe iQ would like to pitch in here as well?

Both Saturn & Juno are about commitment, though in different ways. If they're in opposition, the couple's ideas of commitment might be diametrically opposed to each others'(?) But they also share a common thread, despite the fact that they espouse different ends of it. If they could find common ground in that, each fulfilling what the other lacks, then it could be binding.
The square might be a true 'clash' and take more work, IMO. It'll be helped or hindered by other aspects in the synastry.
