Domenico is a Dom!!!
Eventually, Domenico will wish to have relations with Tatiana, but it's revealed that he himself is a Dominant, and was under the assumption that Tatiana was a sub. Tatiana will get upset and confused, apparently the prospect of a male dominant had never crossed her before. Eva and Eloise will eventually join forces
It'd be mutually beneficial to both parties. Eva has a grudge against Zoé and is determined to get back at her somehow. Eloise has it in for Sandra, who's taken everything she's ever wanted - including becoming Zoé's new protogé. If Eva were to take Eloise under her wing and mold her into a better model than Sandra, they'd effectively kill two birds with one stone.
