I too feel that the actor playing Dev has no screen presence at all. In front of the Goenka family, he looks completely out of place.
I haven't seen Revenge so don't know about Jack but if there is a good reason for his presence, then it's fine but the actor is just meh. I sure hope they didn't bring him in just for injecting a bit of romance in the story because that's not what the show is about.
I missed watching the show ever since his entry. It was the most boring episode ever. And that long chase sequence was so underwhelming.
It's not just his presence either. Even in the scene with Nitya, where they are supposed to be BFFs with romantic overtones, I didn't feel any chemistry between the two. The scene was so forced. And he is a scion of the powerful Goenka family, how could he be away from the country for 2 years. There are just too many loose ends with his back story right now.
I sure hope there is a solid reason for his presence and they are not planning a mushy romance as EHT was suppose to be a revenge drama cum thriller. And do wish the could change the actor his scenes are yawn-worthy and he's ruining the show for me.
