The opposition of Saturn and the South Node almost always means that Saturn is close to the North Node. This is a strong indicator that maturity, responsibility, discipline, career, structure, boundaries, long-term goals, and the ability to manage one's life become part of the future task. The person needs to develop Saturn, but not in the form of fear; in the form of inner support.
The South Node opposite shows an old habit that can interfere with growing up. The native may be used to avoiding responsibility, dissolving in other people's expectations, living without clear structure, fearing power, not finishing things, or depending on people who decide for them. Now life gradually leads them toward a place where they will have to become the owner of their time, work, and choices.
