I think BB might bring her back for some love-angle, because the last few episodes hinted some budding new "friendship" between Upen and Sukirti. And the hug he gave her before leaving, she said: "You are hugging me for the 200th time". Then the SHAYARI Upen said for her, then she said she will miss him a lot. ETC ETC ETC!
So, i think they might bring her back, there are chances!
In my POV, there are TanMaan from last season... Because, they also had ups-and-downs in their friendship. Chemistry from Day- 1, then misunderstanding, then he nominated her, then he upgraded her, then the SHAYARI...
If not Upen, then Arya might be paired up with her. Because he seems to like her. Whatever scene was aired, Sukirti and Arya were always seen together, talking (in the background). And the way he said "Wapas aajao na" seemed from heart...
But, all these might be ACTING, because this season we have a BUNCH OF ACTORS, who are acting 24/7!
So its hard to say what's REAL and what's REEL...
