Angder heard the commotion upstairs, it seemed the captain had found some henchmen. Still, he seemed to have forgotten about him, which he was glad of for now.
He moves down the ship into the brig, and retrieves his lockpick, he places it in the normal hiding place, and then sneaks back to his hiding place in the hold.
Hopefully the captain would see him as just a kid, and let him go on that basis, but he had to assume the worst.
