Some time ago, Markus met with John, a man who seemed to be down in his luck and lost in the big city, not even knowing who he was. As much as Markus wished he had been in a place to help the other man when they first met, the redhead had his own traumas to deal with and had ended up in Europe for a time.
Now, sometime later, Markus wanted to reach back out. Part of him hoped that John had moved on, found his own slice of happiness, or even discovered more of who he was. If not, perhaps now Markus would be in a better place to help him.
After a time, Markus got the hostel's matron to accept that he meant no harm to John, and she eventually agreed to see if the other man was available. Having nothing else to do, Markus would sit at one of the available spaces in the office and pull out his phone.
