i am dead sure the guy in black suit is sagar and most probably shanta also come to know about ganga's past but sagar stops shanta and request her not to discuss ganga's past with shekhar bcoz jhanvi is now shekhar and gudiya's happiness.so shanta changed the letter and in the letter shanta wrote that she (i mean to say ganga) wants to marry shekhar ji immediately.
