Arwen has become better at evading the bloodfest that is the rush for the Cornucopia, though this time she managed to filch a bo-staff without enduring grievous injury. There is a long slash across her left upper arm, bestowed by another Tribute, and some bruising underneath her clothes, but nothing serious enough to put her health at risk.

The crocodile-like thing advancing on her is another matter.

It's small, most likely an adolescent, but even young monsters are capable of inflicting great damage. Clearly, heading south was a very bad idea, and she's backing in his direction; trying to keep an eye on the reptile and stay aware of others in the area who might decide to preemptively take her out.

She wasn't at the council, nor did she mingle with many of the assembly before the Nine left her father's home, so Boromir probably won't recognize her. The pointed ears peeking above twilight-dark hair are a dead giveaway to her race, though.
