Something is not adding up.
His condition has been described as grave. Yet he steps down from the ambulance with minimal assist from just one aide. He then walks to the doorway being led by his hands, but no support. No evidence of oxygen. His gait is slow, but steady.
Me thinks he might be a decoy.

Another view of him getting out of ambulance.
