Surprised the old man can still move 13 years later, he already looked in his 70s in the beginning.
Also, are we really to believe that snipers, automated weapons systems, and chemical weapons couldn't kill Minerva, but some 90 year old man can? Remotely operated drones I could understand, but fully automated platforms? What, did the camera lens looking at Minerva get killed? Did the bullet in the air get killed by Minerva? Did the chlorine gas get killed by Minerva? Dumb.
