Aditya?

Could this Aditya be Nirmala's adopted son coz she mentioned his name in May 19th episode. Nidhi and Aditya are her boss's kids, basically her adopted children. No one seemed to know him when he entered. No one can come attend a wedding uninvited, may be Tiwari's invited them. But Nirmala sent Aditya just to avoid further issues with Malhotras and no one in the family has seen him before. This could be the reason no one recognized him. May be Nirmala spoke very highly of Sumo, a reason why he was attracted to Sumo.
