I did! She didn't only have damaged armor but also some pretty nasty cuts and bruises.
It was most likely from the Pelican crash and perhaps Palmer also had to defend Halsey? Doctor looked pretty unharmed, while Palmer was a sight for sore eyes... She was limping and she was missing whole thigh piece and a knee pad. Also her whole armor had some scratches and damage, but her chest piece and right arm had taken most of it... But even the right thruster was damaged and you could see the insides. You could even see the blood on the armor! And the shoulder pad was lost and her exo-suit was even torn on her arm so you could see the skin underneath - hence the blood. And she even had a shotgun, first time seeing Palmer with a shotgun.
I really want to know what exactly happened after Fireteam Osiris left Palmer and Halsey with the disabled Pelican. As I said, my bet is that Palmer somehow managed to crash-land with it, but she had to protect Halsey, hence the damage on her and Halsey unharmed... But I'd like to know more! I really like both characters, Halsey and Palmer so I'd love to see another comic or a novel or... anything of what is happening at the moment. o_o
PS. It was also interesting that they took away all the lights from SCOUT armor (and many other armor variants). In Halo 4 you could see pretty much every armor lit up in the darkness with some lights on the armor. While it looked cool on Scout, those two lights on the chest piece and the back (there were minor other light like on shoulders and thigh pieces). I can understand that Scout should remain hidden, and lights would prohibit... but it looked cool anyway, haha. xD
