And then there's Solange, an excellent example of the vagaries of genetics.  Robin's blood-sister is *nothing* like herself.  No temper, no violence, no... spirit.

Robin finds it hard to believe that she and Solange are actually related.  She bears so much more resemblance to her cousin-brothers, Jovian and Daeon, than to her actual sister that the fact that she should have... feelings or something for Solange is turning out to be very hard for the Ranger to wrap her mind around.

A feeling that may be mutual.  Robin and Solange met only a few times, briefly, after the knowledge of their shared mother was revealed to them.  And neither of them seems particularly sure of what to say.
