Jo freaks out after seeing the debauchery that goes on in the Challenge

Everyone was surprised/excited to see Jo (San Francisco) on the roster for the Gauntlet II... The last time we saw Jo was when the roommates were going their seperate ways in San Francisco. Well, in the promos for the Gauntlet, it shows Jo talking to the police, being escorted off the property with police officers, and rebuking Ruthie's (Hawaii) efforts to console her. There has been rumors abound about what exactly happened. Highlight to read what happens:

Jo's own friends don't even know she was a Real World castmember, so the chance that she's been catching the last few seasons is slim to none. Apparently, upon seeing the debauchery that goes on during the challenges (sex and alcohol), she freaks out. Her season is still considered one of the most moving, progressive seasons of reality television ever. So, she really didn't expect what she sees when she arrives in Trindad and Tobago. As you saw on the promos, she calls the police and asks to be escorted off the property, because she doesn't trust the rest of the cast.
