Tiger Trouble

The tiger retches, you are forced out of his stomach and you drop out his dripping maw.
"The names Aeryn." The tiger grins. "Now, let's start escaping from this place. He gestures towards some human bones. "Use those to pick the lock."
You hesitate at the bones, former prisoners like you.
Aeryn growls "now or I'll make you my next meal." You pull a finger bone out and chip it until it's a good lock pick. You open the lock to his cage. He pushes the cell door open and gestures for you to be carried. "Get on my back, it will be faster"
You aren't sure if the predator is to be trusted considering you were just in his active stomach.
