I guess its just the speculation on the article's part that La will become negative...coz this serial has never followed the predictable path...so dnt think they'll do that...if they had to do that,they wont have shown her so matured in ystrday's epi...
Moreover i feel she'll end up contributing to the Arhi reltn before leaving...Arnav finally wont have to hide behind a fake relation to express wat he feels for Khushi...same for Khsuhi !!!
