Hi there!
I totally understand your frustration. I'm also not liking Disha hating on Ram. It's really bugging me. But as it's been shown, Ram is unconscious in the hospital and hence he cannot get to his children. He tried to explain to Disha what really happened but the poor kid wasn't ready to listen to what he had to say. Nobody is aware as to where Ram is or what condition he is in. Not even Karan.
My guess is Ram will wake up very soon, hopefully tomorrow but I'm quite sure it'll happen by the mid of next week. I totally agree, Ram should have not listened to Karan. But we can't blame it on Ram, the poor guy just lost his wife and he is totally alone. Karan could've been a good friend and helped him get back on his feet and move on, and take care of his kids. We, as viewers, are totally clueless as to why Karan did something like that. I also feel that he had no right to tell Disha what really happened to Anu. Karan doesn't know the whole story himself, so how can he go tell other people, in this case Ram's own children, that he has killed Anu? Very confused as to what Karan is doing. Hopefully this part of the story unfolds soon, as we're all confused as to Karan's unnatural behavior.
