According to TrueDorkTimes.com (a Survivor spoiler website) they started filming on May 21, 2012, Brenda was voted out on June 25th and the final tribal council was filmed on June 28, 2012. So, she didn't waste any time once she got back to the States.
Thanks — So they have by now finished filming next Fall’s Blood in the Water Survivor and after last night’s Finale they were heading out for the filming of the 2014 Spring Survivor.
It’s small wonder that everyone looks so much older and seemingly more distant from the events of the season. It’s like ancient history by the time it aires.
