How do they plan on retaining characters like this?

Idk what's their game plan with Bajaj and Komolika this season, but coming to Komolika how do they plan to keep her around for the long haul if they've already made her a seasoned criminal within a year of the show's launch.Kzk1 Komolika planned plotted but she always found a way to be forgiven by the Basu's so that she could backstab them again.How can they keep the story moving while making sure that Komolika has a role to play?Don't tell me its going to be another round of murdering, plotting, getting exposed and faking your death, until the next big villain comes in.Also can they at least bring in Indroneel, Komolika's sidekick we'd at least get some comic relief.

Same goes for Bajaj if they r gonna turn him all dark how long can they keep him relevant in the story, if all they r gonna show is tussle between BajRag for Pre. And seriously, is this all AnuPre will do as long as the show runs?Won't they live their life even a little like normal people.I mean their predecessors already had a kid within 1 yr and this AnuPre's bun is still baking in Prerna's oven.
