You're not a member of the gang, You weren't even around when the O'Driscolls captured Arthur. The fact you were able to find him was most impressive. Even more impressive was being able to pass the O'Driscolls unnoticed while carrying most of Arthur's weight.

"How did ya...Ah, never mind...Thank...you" Arthur whispers in a slurred tone as he cauterizes the bullet hole in his shoulder. His senses weren't fully present, but the sight of your blurry face in his vision was enough to wake him...slightly. The sound of the leaves blowing in the wind is a nice sensation despite recent events.
