I kept expecting Emma to ask more basic questions like where are you from? where are you going? What do you do for a living? any people we need to contact about your condition? For a couple of reasons 1) to see if what he says matches any documents found on him or in vehcile, 2) Memory issues, 3) to give the audience more info.
Asking about contacting others would give a heads up about the possiblity of more outsiders coming.
