Simple Reason Guys... Partiality.. Why don't Diandra say anything to her group when any wrong thing is done..
You all remember When GG pointed at bad clothes kept at fresh drinking water and also when Dust-bin bag was not kept properly he called captain and what captain said i can't do anything as don't know who did it.. She could have asked it and cleared it but no.. Then why point out to GG and advice him anything when u can't do same thing with others.
Also GG said i will wash it completely so don't worry so end of discussion.. Why Diandra has to stretch is further.
