Well, this isn't the first time Bela is ready to forgive and leave the enemy just because he is associated with Mahir. The same RJ became innocent, lol. Anu shaking from innocent to guilty there too
For rani position: aghoribaba's task - to find out where is stolen naagmani/save naagmani/clan/whole Naag's world in general, even if Mahir dies - Bela's choice? Going to the bath to cry how she cann't "kill" murderer Mahir - naagmani? Clan? Doesn't matter. If Mahir didn't come, then everyone would have died, but for Bela there is not big loss, yeah - fail
To hand over the crown to Juhi - again, Bela suddenly wanted a calm life and, without a single thought, decided to give crown to Juhi - fail
Now when Bela went for naagmani, so that naagmani would cure Mahir, and leave Vish alone against all enemies with whom they couldn't even cope all together - fail as friend (although it's common for Bela to throw Vish to death as an expendable) fail rani too
Bela should thank Sumima for her love of dramatic spectaclues, otherwise upon returning Bela and Vic would find Vish's dead body in Mahir's room Sumima had no need two hostages she wasn't afraid of Vic or some of his hidden powers, she never loved and didn't appreciate him, so she doesn't have any compassionate feelings for Vic (maybe regret will come when/if Yuvi betrays her for the sake of naagmani or to make maybe naagrani Vish, because from his side jealousy/yearning or devil knows what is it, cos dynamics/tension between Vish and Yuvi they were total dumped)
Vik - his tears for his mother can still be somehow explained. But his reaction to Vish's death and comeback that's the aught! To begin with, it doesn't bother him that the very same love for which he is crying now, he recently left to die alone with a smile on his face, nope! It doesn't bother him that he strangled the very same love, nope. Not to mention about manhandling and verbal abuse generally. Vish regain consciousness, Vik's reaction - never leave me. He isn't angry at Bela, nope. He doesn't think that they threw Vish to death, nope. There is no over-protection reaction like - you will not go anywhere, you will not do anything, you will sit in a safe place, and don't take in head to object, nope. Everything is cool, Vish on the verge of death - it's success, let's play the ghost. Vik loves Wish? Don't make me laugh. He is too busy with the mission to save Bela's love to love someone by his own
Vish the only not ruined character? Come on, from the moment of the wedding with Vik it was shot after shot in Vish's head
"I will not ask/beg for love. No way. And then after that these tearful - "Why did you reject? And even after that I love. It doesn't mean anything at all? Tell you love for once - this is absolutely out of Vish's character! Original Vish would never say such nonsense!
And the fact that they give Vish a phrase like "I will not ask / plead for love. No way" /this's already total nonsense!/ does not alter the fact that they forced Vish to say absolutely opposite nonsense!
Not to mention how stupid they forced Vish to be - first to glorify Bela, then to glorify -Vic, then to glorify Sumima, then to glorify Yuvi - shot after shot to Vish's head again
Mahir - the whole track of Mahir and Vish wedding was only to get Vish out of room/marriage with Yuvi. Either it was necessary to keep the dynamics Yuvi-Vish, and then Yuvi would never let Vish out of either room either marriage or stupidly escape from the situation that they did
Sumima wanted to divide Mahir and Bela, and plus Sumima strongly strained the increasing Vish's influence to Vik
By the way, Sumima's words on the cliff "My son fell in love again. And I didn't notice is also from the category of sheer nonsense - Sumima very well noticed if she hadn't noticed she would not have been to shepherd Vish and Vik. And she definitely wouldn't have caught Vik in Vish's room Sumima knew that Vik would come to Vish, she knew that because of Vish, he could go against her. Sumima knew very well that Vik had fallen for Vish. It's Vik didn't know, although rather he eagerly didn't accept that he had fallen for Vish. For Vish he proved that he loved Bela. And this conflict/dynamics between them was really interesting, but here everything was ruined by three scenes - cliff, a conversation haveli after leap, last Vish's wish
It would be much more plausible if Vish didn't believe in his love, considered his love a condescension, in the end he knock his love for Ruhi to Vish's head for years and years, but alas-alas
Between Vish and Vik was relations dynamics/conflicts/tension, now it's just a pale canvas. Both Vish and Vik are stupidly expendable for an indifferent Bela in her desire to have Mahir and to preserve her status quo/rani. For Bela they just cannon fodder
