Season 2 Ep42. The opening scene shows a "ragged kid" fleeing from a black-ops Chosen armored vehicle. He makes it to the Hotel where Ellie is trying to get in to see Jack. Now can you see any difference in his makeup? Try really hard.

Look at his arms. In the first scene his arms look bare, heavily painted. By the time he gets to the Hotel he has a dark red top under his yellow-green tank-top tunic.

BTW the actor is James Ordish who will play Andy in S3.
