Is bela's revenge connected to Andy?

Hello naaginians ... actually I am getting a very strong feeling that ruhi's revenge is sidetrack and bela has her own story connected to Andy Sehgal because he seems to be quite villainous and his wife sumi too is a vamp! Moreover Ruhi or vish's revenge seems to have many loopholes like in previous series the murderers were justified ...like in s1 all killed shivanya's parents together and in s2 all killed shivanya together! But in S3 only Yuvi shooted and some other Sehgal sons but some were not much included like that girl...death is a very harsh punishment ...and next thing is misunderstanding about mahir...I hope they won't be making it as Bela v/s vish ...ie Bela saving her husband blah blah...m really excited to see Bela as nagin!
