I was deadheading in the cabin when I was asked by the Captain to come to the flight deck due to an [urgent situation]. By time I reached the flight deck the number two engine was already shut down. I assisted the primary crew anyway possible to lessen the workload and stress. I assisted with cabin and airport operations communication; checklist completion; and any other tasks the crew needed help with. The primary crew did a fantastic job and needed very little assistance.
