a short update please

Ok guys..DONT HATE me for asking too many questions..I have recently moved from one state to another and I didnt have the dishnetwork for quite a long time..I only had ZEE and TV Asia so I have missed TOO many episodes of Kkusum...Now Im watching new ones and am a bit confused..hope u can help me..sorry 😳

-why did Mahi turn evil and how cum she is alive?

-I know real kksum is kidnapped by Mahi and Sawti(but who is Gautum??)

-Is Kali married to Kshtijh's younger brother(cant remember his name) and Kumud married to Kshetijh? IF yes then what happened to Gurv?

-where is Sonu(Nikita's son)? and where is the new gal who Sonu liked..umm...Vedhi??

-dont u all feel that the new gal who is playing KKusum's role is too young to be a mother of Kumud(who looks older then her the new kkusum)? I think the writer plus ekta kapoor is gone totally mad now..they just want to drag the drama and they dont care who play's kkusum's role..Im sorry but I feel this REPLACEMENT of Kksum is totallY DUMB..I never liked the previous gal but this is TOTALLY dumb....I wish it was Nausheen..but

hope u guys can help...
