A genuine love triangle in my opinion would involve two women/men in love with the same man/woman and the man/woman in question having divided feelings about the women/men in question. If that is true, there have been no genuine love triangles in KS at least none involving our beloved jodi.
Early Days- Jan-Apr
B-P-P: Bani and Pia both flat over Pooch but Pooch had no romantic feelings about Bani, the kiss on St. V day notwithstanding.
J-P-P: Again, no show, Pia not remotely interested in JW.
J-B-P: Pia not remotely interested in JW, JW not interested in Bani, Bani falling gradually for JW.
Mid-game: May-Dec 06
J-B-R: Bani head over heels in love with JW, JW gradually falling for Bani, JW's interest in Rosh merely for old times sake and possibly threat of blackmail over PR. Closest thing to a triangle, yet but not there really.
J-B-Pooch: JW suspected Pooch and Bani of carrying on briefly but that's about it.
J-B-P: Whatever interest JW had in Pia was purely bcos he had accidentally "fathered" her kid and was being blackmailed, JW hated Pia otherwise.
Future:
Whatever JW and Bani may feel about each other (hurt and betrayal on Bani's side, guilt on JW's, roles may get reversed when the TRUTH is out) and profess (publicly and to self) about each other, it is unlikely that they would ever be in love with any one else. A J-B-T/J-B-Pooch triangle may be contrived/suspected but let's face it, Tarun and Pooch are not even a pale shadow of JW and whatever be the two elder Dixit sister's faults they have a good taste in men.
A more formidable contestant (which could perhaps test even JW and IF loyalty) would actually be Sonali being thrown in particularly if St. Billo was to banish JW from WM and Bani's life. Sonali, if her character is not perverted by Mayee, is one person who can give Amma a run for her money. She was genuinely in love with JW, gracefully made way for Pia and sheltered Bani from JW's wrath in the initial days b4 vanishing. If she comes back, is unmarried and finds JW in the dumps will defo give support (not Pia's type) to JW. And that would really make Amma nervous and insecure, even if she claims that she is over JW. And will be even more so if JW is proven innocent.
Would love to see Sonali back in KS, still in love with JW but as a positive character .
