Sun Saturn Pluto can also self-select those they will feel estranged from. If you consider the sun - the vital core of self - the way we function in life - and pair it with saturn or pluto or both - there is selection process that was ingrained at birth - issues of trust/betrayal, hardship/growth.
In general, when we find those who we are most uncomfortable with, usually due to our own recognition of hidden/restricted parts of ourselves, we tend to react unfavorably to them, when in fact, they are in front of us, like mirrors, to reflect back a familiar image that, usually, Neptune, likes to change with sun on an on going basis for the sole reason of not having to confront it by running away from it or denying it.
The great thing about the sun/saturn/pluto is their absolute ability and power and fortitude to deal with it all.
Sun Saturn Pluto has the ultimate challenge of de-compartmentalizing self and others if they are to find the trust and growth in themselves if they are to realize the great potential of such a trio.
