I don't think that Gideon has "mummy issues " in relation to who he's dated
I think he loved Corrine and from their break up was looking for someone like her , hence he looked at brunette
Then Eva changed that when he saw her look in awe outside the crossfire building . Time to look at someone different. Then when the met inside she saw through him. I think from that moment Gideon knew he would pursue Eva no matter what the cost .
If Gideon has mummy issues it because maybe he feels hat the arguments his parents had pushed his father into committing suicide.
Maybe he blames his mother for his fathers suicide.
Or was hurt that she married Vidal so soon after and had children with him .
