Radha has always been shown to be an extreme character. Don't you remember when she first first introduced, she was all pro Rashi and anti Gopi. Then she became anti Rashi to the point where she almost destroyed Rashi's marriage. Then she become pro Umang where he was her entire world. And now she's anti Gopi and determined to destroy Gopi's life. I think she might have psychological issues. It couldn't have been easy to live with a mentally challenged mother (remember Madhu went "mad" after Gopi left and wouldn't let Radha be out of her sight).
And yeah I'm annoyed at Koki too. She is meddling way to much in this matter. I'm almost convinced that it was she who battered in Ahem's head the thought that Gopi killed Meera. She needs to butt out or go to those long needed anger management classes.
Ahem, to a point, he is justified. Gopi was wrong in keeping a child from her father and a father from his child. Any sane person would be angry to find out that they have a child whose life they completed missed, and not on purpose. But I do have a problem with his blaming Gopi for Meera's "death." I'm hoping that Ahem learns to forgive Gopi and they actually live together happily before they find out that Gauri is Meera.
