LAST EDITED ON 04-21-15 AT 09:32 PM (EST)Do we know for sure if they're posted in time order or is this a guess?
The reason why I ask is that the picture you have labeled as #01/0021 shows several contestants wearing their TC clothes and some have their bags with them. If you look closely at Sierra, her chest area seems to be blurred - hiding the immunity idol?
As well, the pic of Mike and Dan together (#20/0019) shows Dan with his bag and another pic (#17/0020) shows Carolyn and Will in their TC clothes. These three pics I've highlighted are 0019, 0020 and 0021, the last three pics of the press photos.
