I haven't quite figured out what the actual "call out" was about.
Did Yalie actually lose his money? Did Mark refuse to send the gun? Did Yalie ever contact Mark in a normal fashion and tell him how upset that he was?
This was my response last year, and it would still be my response this year. I don't think the simple questions were answered then or now, by either party. Mark has certainly dug himself deeper in the interlude.
