Alice foresaw the Volturi's decision to visit Forks, and explaining that she was not trying to predict their actions, but trying to find Irina, Bella came to the conclusion that Irina assumed that Renesmee was an immortal child and that she must have decided to go to the Volturi to tell them about Renesmee. Irina was with the Volturi when they arrived in Forks to punish the Cullens. She was called upon by Caius to bear witness to Renesmee. She explained to the Volturi that she was upset because the shape-shifters killed Laurent, but the Cullens refused to let her avenge him. However, upon realizing her mistake, she no longer wanted to complain against the wolves or the Cullens. The second she said that she was willing to take full responsibility for her error, Caius signaled the guard and Irina was destroyed in front of all the vampires present. Caius merely looked on and proceeded to set Irina ablaze, as a plot to enrage Kate and Tanya into attacking the Volturi guard. Caius later justified this by saying that "now she has taken full responsibility of her actions".

Laurent had no mate until he left James' coven (the American nomads) and followed Carlisle's suggestion to go to the Denali coven (tanya and her family) where he met Irina and became her mate.
