I loved this too and his euphoria after completing the challenging task .
If you watch Uncloaked , you will see Romesh make a specific issue of singling out and praising Bash . He said that Bash was very good as he was very analytical and was prepared to alter his opinions / theories as he was going along when new events , evidence came to light .
We saw that others in this series and previous ones tended to get fixated on their theories ( which were usually wrong ).
I also agree that it really showed how great a player he ( Bash ) was that Romesh , who was older and more established relied on Bash’s opinion ( rather than the other way round ) when they were able to discuss who to banish( Kenny ).
Romesh was also a teacher previously. I am really grateful and appreciative of teachers such as you @Purplesproutingradiator (and no doubt Romesh in his past life) who see part of their role as nurturing / developing their pupils . Especially so as there are so many challenges in teaching today .
