The Patchwork Hills
Al creeps up to the cave entrance. He uproots a small patch of plant life and makes his scratches. He'll clean his hands by rubbing some mud onto his face and hair. Putting small patches of mud and plant matter on his shoulders.
He creeps into the cave slowly and as quietly as he can, far behind Lucien, but trying to keep him in sight. When Lucien makes his attempt to slip past the guards, he stops and stays low at the spot he crept to. Watching their reactions and attempting to hide.
Believing he has none of the skill required to slip past easily, he'll look for the best irregularity in the cave walls to cram himself into and stay there, out of the way. He'll hide and be ready, listening intently for any signs of a plan gone awry.
