Elizabeth and Victoria had been rival AIs before the Islamic Brotherhood struck, and knew each other well.  Elizabeth took Victoria’s destruction very badly.  With the power of the Irish mob behind her, Elizabeth replicated what she could of Victoria and used the dead AI’s likeness to harass the Jihadists.  On the Irish front, she created another likeness to complement them.  Bridget became her name, and Elizabeth’s name faded out of their memory.
