Vote Analysis, Aaron Exit Interviews

Vote Analysis
Erik, Jaime and Peih-Gee all voted for Aaron - no surprise there. However James and Aaron split their votes. Aaron voted for James and James for Peih-Gee. Why? Wouldn't the two of them have been better off if they had voted for the same person (say Peih-Gee) and tell Erik that if he wants to shake things up then he can vote with them?

Aaron's Exit Interviews
Here is what stood out to me from reading several interviews with Aaron after he was voted off Survivor: this was the first time he ever applied to be on the show and he was on a flight to China roughly ten days after he bumped into someone from casting! Really?
