I believe Prem was one character which could have been moulded in any manner. He could have been shown a carbon copy of Sahil in terms of business and Neetu in terms of wits...or he could have been even worst...two steps ahead of his parents...
Another scenario could have been using Kalpi as a trump card against Raghav but eventually falling in love with her and a perfect and revengeful love triangle
Or even better after knowing his parents deed he could have turned out to be an extremely positive character.
Honestly in the whole show only Prem's character had ample scope to be moulded in whichever manner CV's wanted.
Prem's character could have been ruthless or heartbroken (Kalpi chooses Raghav over him) psycho,dangerous gamer and a perfect one to have battle with...but but but Priye...CV's ko serial chlanr keep liye creative hona pads aur jo pehle kabhi nahi dekha who hua...chalte serial se character woh bhi villain ka (In other serials there are dozens of villains and one or the other keep on coming on the screen to create probs for leads)gayab kar diya gaya...wow...ye creativity ke liye to inam banta hai boss
By the way nice post👏😉
