Quote Joyrider: Nikki will not shun Adam's baby because she will want the family to accept HER child into the family. She will convince Victoria to accept Adam's child and Victoria will convince Nick. Nikki will work on Victor getting him to accept his grandson so Victor will accept her child too.
I don't think that was Nikki's intention, she seemed truly concerned for two kids, Connor and Summer, being caught in the cross fire of Victor, Adam and Jack. At least, that's what I saw.
