Perhaps that was tied up in the core of it for Wash; he'd had that, had it for one perfect moment before Epsilon had realised who he was, what the Director had done, and killed himself rather than stay in Wash's mind and maybe let him help. In any case, he keeps the AI unit close to his chest, cradling it protectively. How could he do anything else when he remembers Delta's creation?

Maybe it's stupid to let Delta speak, but he does. "Yes, I am aware," Delta replies. "Unfortunately I am unable to access any of their system."

"We recovered him," Wash says and he holds up the unit towards the camera, displays the tiny chip. "Unharmed, undamaged once we got the codes to deactivate him. Control sent it down when I found you."
