As the newcomer accosted this Julia, Markus backed toward the door that led back inside. Apparently this girl wasn't necessarily on the same side. The mystery girl that Qubus rode on didn't know her, and if Qubus' companion didn't know her, probably Qubus didn't either. Markus didn't know what that meant, and so was moving to where he could make a retreat if he needed to. It was something he was good at, being a fencer. He knew where to stand if he needed to retreat, and he knew when that actually was. 

But it didn't come to that, Julia fled, and now they were on the roof with Qubus. Markus could only hope that he had chosen the right side, now that he was unsure how many sides there even [i]were[/i].
