I read in the preview of Apr 29 episode that Kulwant will come back while Sukhi and Geet are getting married. This marriage will void since it happened while the first husband was alive and they were not divorced. That makes me feel better that Kulwant didnt take very long to come back (while Geet started living with Sukhi or falling for him). I was afraid that Kulwant might just leave seeing his wife getting remarried or they will show the track just like movie "Deewana". I am so glad that it didnt happen this way. They can simply say that this marriage is not valid.
this is the true beauty of this great drama. This is why I love MMDR coz it doesn't stretch anything unnecessarily to increase its number of episodes like other dramas do. However it makes me worried to think that they can wrap up the drama within short span of time
