I have a feeling that Aditi who visited Popatlal's house is the same women who played role of vegetable-hawker ("Sabji wali") during Missed calls episode. It was she who called Poptalal on Babita's behalf to arrange a meeting which finally solved the "missed call" issue.
Two premises led me to reach the above inference. These include:
(a) First is here face itself (although this is difficult to analyse without her many bindi when she was a hawker.
(b) Second, is the way she says "acha acha''...very very similar tone and accent as that of "sabji wali".
Anyways...this is just an observation to share...
