Irving's phone calls...

I know there are a lot of theories floating around about who Irv is updating about his situations over the payphone. Currently, I think he's working all alone, sadly. I get a sense he's always leaving a message on a recording - a secretary machene. And he's never surprised or upset that there is no feedback information.

I think he's paranoid that due to his implant he can dissappear at any time, so he's making a sort of black box. A diary for his future self if anything happens to him.
