Jack: (about Irina) She was putting on a show for Cuvee. Before she left, she put these in my hand. She told me they're using the cores to activate a Rambaldi artifact.
Sydney: They're not detonating the nukes?
Jack: Among the things Rambaldi experimented with was self-sustaining cell regeneration. This artifact they're opening today is reported to be Rambaldi's proof of endless life.
