After the HYDRA Uprising he conducted job interviews with out of work S.H.I.E.L.D. scientists. Diaz, along with Ott, met with Phil Coulson and Melinda May who were trying to obtain files from Cybertek. They turned them down for employment because the technology they presented, an I.C.E.R. bullet, was already given to them by HYDRA.
