(This seems to be a severely Wounded Guardian.)

Player: "How bad are your injuries?"

I can barely move...

I think... they're quite serious.

Player: "Don't try to move, you'll make your injuries worse."

I won't last much longer... without medical help.

Find Medic Marke in camp... she'll know what to do.

Player: "I'll find her, don't worry."

Oh, Player. Did your injury from before get infected?

Player: "No, I'm fine. But there's a wounded Guardian nearby."

Several Guardians were overrun during the fighting south of here. You must've seen one of them.

I'll go help him as soon as I can. Here, take this for your time.
