Just curious on a few points: 1) How would Oriel know it is specifically Cale's craft? It doesn't have any unique markings stating it is the property of Baltimn or differentiating it in a physical manner.
2) How would he be able to spot him in the undercity? That's a pretty dark place and more than one person owns a StarViper.
3) How did Paul pick up Cale's presence when it is Atropos in there at the moment?
