For a moment, Altaïr was concerned that Alain had decided to shoot him in the head to save himself some trouble. Being told to stay still just made him want to move more. Luckily for Alain, he still couldn't do much more than crawl.

"Take it. I cannot stand." It took much to admit he couldn't.

He picked up the mask and gave it a gentle toss. This could mean potentially losing access to his power, if Alain decided to take it, but Altaïr's training had been designed without that in mind anyway. He would rely on good old-fashioned training and adaptation. Al Mualim would be pleased if he could see him now (or perhaps punish him for being caught).
