Apara Mehta in Doli Saja Ke?

When did Apara Mehta (Savita, Kyunki) (Kaki Sa, Saath Phere) join Doli Saja Ke? And what is her charcter like?

So far she was in one episode. She played a kothewaali who is blackmailing Shardaji since she knows Chaitanya's birth secret. But since Chaitanya' secret is out, I don't know what her role will be. Maybe she just had a guest apperance for one episode.

i too think that it was just a special appearance
