Two things about Tatiana : She is so jealous of Eva on many levels; first of all her relationship with Cary and second of all because of her rich gorgeous boyfriend Gideon who clearly adores her , third of all because Eva is gorgeous and NICE which Tatiana clearly is not!
Also, I think Tatiana is Czech not Russia because remember she was in Prague for a short time...I don't connect Tatiana with the Russian mob but I do connect her with Deanna and I have stated before that she clearly has $$$$$$ in her eyes by hooking up with Cary and by that association Eva. I can't see her ever delivering that baby if she is indeed pregnant models are too concerned with their looks for their livelihood and if she is still in her peak earning years she would never jeopardize that. I think she played dumb at first as to who Gideon was but I think she knew he was Gideon Cross the MOGUL right from the start!!
