Camila Brait has been with NT since WCCH 2010 at least. She was considered the next one after Fabi. She played at WCCh 2014 às starter.
However leia delivered really great at World Gran Prix 2016 and was listed to Rio 2016. So Camila was cut in 2016 and 2012 ( she traveled to london in the case of Natalia Pereira might not be in condition to play, so she was the last one to be cut at London 2012).
The libero who you are talking is Gabi Guimarães (world gran prix 2017 winner), she had an injury and are currently playing in SESC RIO, but she is not part of the starting seven.
He's talking about Fabi, not Gabiru. Notice the "super-amazing".
