The person in the picture is Lionguard Inspector Ellen Kiel. That image was used as the banner image for the Secret of Southsun game update, which you may have already seen here: https://www.guildwars2.com/en/the-game/releases/may-14-2013/
If you recall, Kiel was sent to Southsun Cove to investigate what was happening there due to reports of increased aggression on the part of local wildlife and tension between the refugees from the Shiverpeaks, who had been displaced by the Molten Alliance during the Flame and Frost story arc, and the Consortium who offered the refugees a new start as settlers working for them on Southsun Cove.
We first introduced Ellen Kiel in the Lost Shores game update last year. After the defeat of the Ancient Karka, Kiel remained on Southsun Cove to maintain order. So when the things started heating up between the wildlife, the settlers, and the Consortium, Kiel was assigned to take care of the investigation.
As far as the question in the thread title, that remains to be seen, but good on you for catching that.
