Ok...so Rohan has known about Heer Being a kinnar since he was like 10 or 12 and she 5 ? He accepted her being a kinnar and has always loved, respected and protected her. Soham has also loved and protected her ...but his disgust with kinnars has overshadowed his love for both heer and saumya. From the precap ...we can see that he has not coldly or ruthlessly tried to kill heer...he’s crying and is shown upset..while taking out the oxygen mask......so he still loves his sister....but his prejudice against kinnars, his masculine pride is overshadowing and dominating over his brotherly love..This is similar to the way harak Singh behaved when he found out heer was a kinnar,..he also tried to kill heer....he wanted to throw her off the cliff..but his love for his granddaughter won and he accepted her,..So I think it will be the same with Soham..but at the moment Shanno dadi is also stirring up his emotions ...So once he is set straight about his father and Shannos influence on him is reduced ....we should see a change...And hopefully we can see Soham, Rohan and Virat all become Heers supporters and protectors...😀...The scene where Soham went with Heer to virats house begging for his sisters happiness was so special...it showed how far a brother will go for his sister...I want that Soham back.
