Since the memory loss track started, I had a hunch that Anurag was faking it. My doubts were solidified when Anu says to Prerna- Sonalika mujhse shaadi karke pachtayegi. It was not something he would've said for his wife. I couldn't think about the reason but it may be to prove that Sonalika is Komolika in front of Police to get her arrested. I have a strong feeling that this plan of his is going to backfire as the theme of KZK is that AnuPre are separated due to misunderstandings. Though he may be doing to this to protect Prerna from Komo, but going by recent record, all his plans involving his ill health backfire be it his deliberately getting in front of Bajaj's car to frame him but himself getting gravely injured. Though he could be doing this to protect his and Prerna's family, but his not confiding in Prerna can prove to be the undoing of their relationship.
