I'm going with one of these three, personally.Batman wrote:Technically we don't know the ISD didn't pursue, we just know the 'Phantom' got away. There's a number of possible explanations (none of them mentioned in the episode naturally) for this-
1. As RI noted, Stealth. The ISD either never noticed the ship leaving to begin with or lost it sometime during pursuit-the 'Ghost' is extremely stealthy and it would only make sense to use the same technology in the 'Phantom' if at all possible, and the name 'is' something of a hint...
2. They did successfully pursue but not in time to prevent it from jumping to hyperspace (nuCanon Wars ability to track ships once in hyperspace without a homing beacon is at best undetermined)
3. The Inquisitor's orders said 'do not get involved until I say otherwise', and with the loss of the shuttle he no longer had the ability to tell the ISD otherwise
And really, who cares? Escaping the ISD wasn't the point, not really. They either avoided it or managed to escape in a chase. But we'd seen them run from TIE Fighters already at the start of the episode, and even the pair of ISDs with the Ghost so why waste precious air time on repeating a similar scene?
Better to see Ezra dealing with his Dark Side dalliance, finding out that Hera knows something about his parents (and that she and Kanan are having a discussion about the kid) and of course Sabine giving him a nice little pick-me-up at the end.
