Barkha was a recurring cameo- a really famous lavni damcer from gadchiroli too. Sai knew her long ago. Barkha used to come every holi to perform lavani in CN. They met there in Sai's first holi and bonded immediately. When Sai went to GC after being ousted from CN by V due to devi-pullu kaand, Barkha learned all about Sai V equation and was there to offer her counseling and himmat in life.
Recently when Amba revealed she was a dancer, Sai says you are not nachne waali but a graceful lavani dancer and tells her- do you know Barkha. amba says yes off shes so famous, but how do you know? Sai says she was a woman who gave me courage. Sai sees Barkha as a strong woman who had the guts to build her unconventional career despite objection and insults from people.
Hope to read in FFs what is not happening on the show.
