Well, if it took 12 rounds moving in a straight line at 360" per round... moving along the city streets at a normal running pace... at least twice to three times that long... so Adrian is on his own for something like another 20 rounds, assuming that Wren finds everyone fairly quickly and gets them moving... The GM can shorten that, of course, but I thought that Adrian was just going to watch them, not engage them all by himself.
