I was surprised to hear Probst use the nickname "Skinny Ryan." In the past he has been all upset about demeaning nicknames. Skinny clearly wasn't intended as a compliment – it's the excuse they used for voting Ryan S off.
Sure, Ryan S sucked at the RC. But he performed better than the non-swimmers *coughOstencough* who didn't even participate.
Ryan was booted because of his lack of social skills, not merely because he was skinny. Rob (S6) was also physically weak, but schemed his way to final 3. Lillian, despite her lack of muscle, has also earned the tribe's trust.
But even so, maybe they should've let Osten go. A non-swimming whiner with no body fat reserves is not an asset in a pirate themed game. There are going to be a lot of challenges involving swimming. And others involving intellect. Neither of which are Osten's strong suits.
On TES, Ryan S said that his troubles with Andrew started when Andrew gave him the tribe's cash to hold. But they showed Andrew jumping off the ship with cash in hand. :
