Dev's statement abt his mom's struggle looking at that knife in the box...during difficult times ppl collapse or they give in ...but my mom did neither she fought keeping her head held high !!
Khathri's statment to Ishwari , the day your son knows the truth , ur image will be lost in front of him
Flash Backs , if I remember it rt ...
1)there was scene in which some one comes and tells her that she needs to pay the house rent or she will be kicked out. And she was able to pay it...they never showed how she got the money
2) Another scene in which Khathri says that she just has to give in and he will take care of all her needs...we see her crying and standing there scared
They have also shown Dev confronting Khathri and telling him not to come anywhere near his mother or his family ...so this means Dev knows Khathri..
Now having said the above I feel she might have had to compromise or might have done something morally wrong for the sake of money so that she can safe guard her kids...
Coming to the present track...Dev might blame Sonakshi for making use of Jathin during the struggles of her life in those 7 yrs...and might question her moral values ...and tell her how his mom had not taken any ones help to bring them up...with out having to give to such immoral ways
So again a parallel track...
You know what ...these are my predictions...I am sure our CVs will have a surprise out of this as well...
