Elser questions why Harry would make the effort to fly all the way back to the UK to attend the court case, especially since he has previously stated that being in the city triggers him.
She also notes that while other claimants in the case used the side entrance, Harry used the front entrance, which seems to suggest that he was making a point.
Elser believes that Harry's appearance in person was a way to ensure that the court case received serious publicity. If he had stayed in California, the legal matter may not have been covered as energetically.
Elser also thinks that Harry's relentless criticism of Fleet Street is not going anywhere, and his court appearance was a way to hold their feet to the fire and make a publicity coup.
Overall, it seems that Harry has a strong motivation for attending the court case and is using the opportunity to make his opinions known. However, it remains to be seen whether his efforts will have any long-term impact.
