In his introductory scene, his philosophical outlook in yesterday's episode all are so similar to Sid. Sid was a painter and philosophical, calm, composed man in Dil Chahta Hai.
I am not sure about how Omkara's character will unfold further but from what's shown so far I see a lot of resemblance to Sid.
On a lighter note, how many of feel Shivay and Omkara got exchanged at birth or got gene transferred 😆 Going by the precap Shivay is a lot like Tej, also dadi's description of him as initiating relationship even of hatred with only equal wealthier and status people rather than with the people of equal virtue.
Omkara seems to be valuing more of virtues than wealth, which seems like Shakti, though not sure of Shakti's real face yet.
