Why don't they first solve old mystery

This is way too twisting . Have you noticed in this idiotic serial , They never complete old mysteries and just keep starting new ones . As in Mahi's true colours haven't been revealed , faking death........while faking death she kills a woman( whose body they show being thrown from above.Then she kills another guy in a hotel room ....who also falls from the window, Kusum sees the murder take place and her memory comes back .....but she forgets that murder she witnessed.
Then what happens to other 2 wives .....who come in do bad things and disapear.( that Rimjhim girl her son and also Shweta Kawatre)

Don't you think they are perpetually adding mysteries and not solving any of the old ones ???????????????????????????????????????/

you know why she's making new stroies....so ppl can foget old ones...Ekta does not any of the answer of old stories...she does nto not what to do....she's a brian less woman....
