Here are my theories
1. Anne Lucas and her brother Hugh are the shrink and doctorate who were treating the Vidal family during Lizzy's pregnancy with Ireland. Hugh, we now know abused Gideon. Lizzy, is still seeing Anne for treatment.
2. Anne is stalking Gideon at functions, turning very dangerous, to the point of endangering Eva.
3. The two women suffering from depression, that Anne mentions at the end of Entwined, is herself and Corinne.
4. Monica is mixed up with the mob, over gambling debts left by husband no.2. Leaving Eva at risk. That's why she was tracking her, and constantly obsessed with money. Never wanting to be poor again.
5. Monica will admit to being a high class escort, to pay her bills when Eva was a baby/young child.
6. Mark will end up working for Gideon with Eva, on the 10th floor.
7. Gideon will make good his promise to destroy any journalist(Deanna) who prints anything about Eva's
abuse.
8. Monica was at the apartment paying off Nathan, the night he died. As she was leaving Monica sees Gideon, who had arrived to kill Nathan, Monica saw Gideon do the deed and leave. Clancy removes the bracelet after Gideon leaves. To plant on Yedemsky(care of his brother in the FBI).
