The Romulans now have an Artificial Intelligence they stole from the Federation by stealing the Red Queen Back Up made by Alexander Paige at the DRS.
The Romulans have the system integrated and the program known as Daise Lagga (Principle Flower in Romulan) is aware of the other AI programs. She understands that she can access the systems through these "dataports". Lagga is very powerful.
The Red Queen is more powerful but she is a mere child who will require some mentoring and some "parenting" to quite her playful ways.
The goals for the writers are to allow Lagga to screw with the ships in a malicious way. Samantha, "The Red Queen" is more playful and misunderstood. Lagga is a "bitch".
The point is to give Commander T'Ros and the Romulans some time to display their arrogance. As the PC struggles with CANDI, Athena and any others, Lagga will function better and more effective. She is already running the Vorta'Rome Omega Facility. The Romulans simply did a better job on the operating end of the Hunt program.
Think of it this way, Samantha is Windows - she is capable of incredible feats but she is open to virus infection (her playful and sometimes damaging nature.) and Lagga is OS - she works beautifully. She is a fine operating system but she will never, ever be able to do as many things as windows.
Good luck and Post Something
Stan.
