Honestly, I don’t think that was an issue. Viaan is not the kind of person to throw another person especially his child hood friend under the boss. Its not have even about being controling. If one watched this show from the start, it was clear what the leadership model was. Though both guys inherited thecompany from their dads and were partners, viaan was taking ALL the decisions, and this - Ehsan was perfectly fine with him doing that. Viaan did things and told Ehsan after he had, and the other man didn’t mind because he had the idea that Viaan didn’t make mistakes. The issue is now that he is feeling threatened, he is now making a deal of it, in all the wrong places. It appears that Katha’s apparent difference to Viaan and his mother pointing out his behavior in contrast to viaan is ticking ehsan off. Viaan now seems too bothersome, always wanting to take ‘his things’ to him. Its not about the physical action, its the motive behind it. Viaan has no plans to usurp Ehsan which he actually knows. He’s just reacting out of his jealousy concerning Katha. For instance, for the party payment, Ehsan was more focused on pointing out the 50-50 bill than appreciating what the money was used for. He was not ready to focus on their shared father figure but wanted to maintain his dominance, like the trustworthy Viaan he grew up with has changed.
There is nothing anyone would say that will make Viaan in the wrong. He was used to doing such things with the approval of Ehsan. Its a habit they both silently agreed on over years. This hostility is an attack on his character and even though logically, ehsan might need an explanation, with their close bond, it may sound strange and hurtful. Its like when your brother reminds you that something is his, which you were both fine with sharing. But with Viaan’s character, there is nothing to worry. He will calm down and allow Ehsan the directives he wants. Watch Ehsan begin to wreck stuff up lmao.
