Barun did try out 1 yr sitting outside and doing nothing. By now he must have woken to the realities of BW and he now knows how things work out in BW. So if he were any intelligent he would grab an offer with the channel itself and try to come on some show. In IPK time I never saw any one pointing any leaves that Sanaya took, even Mishti always mentioned when barun was in and out of mumbai but she dare not say anything about Sanaya because she was channel contracted. And seeing at the number of body doubles for Sanaya in the earlier episodes, I am sure she must have also taken some leaves in between but there was a hell on IF only when Barun took leave and that was partly because of the spoiler girls. So it is better he gets under a channel contract and not with a PH because he gets paid better and he can negotiate better.
So looking at both of them, I think both will benefit from each other and it is better if they bury the hatchet and move on forward.
