RK is still chakki peesing and peesing in Jail

His so brazen he took Madhu there thinking I have the tattoo now the same like RK she won't believe RK, but before they got to this stage where RK is in jail, RK told Madhu to keep asking him questions about their private past (not known to the newspapers) to check if it's him, before he told her this she asked him about the song before Bahon Ke Darmiyan and he confirmed Dadi Amma, this neither of them told anyone else, the newspapers reporters or Kuku doesn't know this, so I was thinking RK would say that to her, Biwi the song playing at our Karwa Chauth date before was dadi amma, get her to remember this is what she asked him to check if it was him. Perhaps it happened too fast she was there all of a sudden and she was gone he couldn't remember what to say to convince her.

Yes he said to ask him anything, as the duplicate wouldn't know, because he must have remembered that question about the karwa chauth song, but he should have told her the answer to her previous question when she was checking if it was indeed him in the bedroom after the havan puja. But it happened so fast one minute she was in front of him and the next minute left, KRK did say everything about us is covered in the media so anything about her past the duplicate would know, that made Madhu confused that they is no way of knowing by questions, but like that karwa chauth song they didn't tell the media about that dadi amma did there? Similarly Kuku Bhatia won't know either, so both RK and Madhu should think how to convince her it's him.

It's interesting what possible logical way is there for RK to come out of jail alone? I think it will be Dipali or Madhu to break KRK and know he is not RK.

I don't know she's left from there thinking that the one in jail is very passionate like her RK, the one with her is less so, so maybe it will get her to observe closely the one with her to see if she can catch anything else odd.

It's really hard with RK because he is unpredictable what he will say or do from one day to the next, so it's understandable to me why she can't be sure this is KRK. We've seen RK doing puja for his dad without the family telling him to do it (Sitara Studio havan puja), we have also seen him doing puja at the start of a film he was doing on the next day of their 4 phere shaddi, so he does do religious rituals when the mood takes him, so if he comes now with tilak on his head or recites a few prayers to get Pabho to eat again and talk to him when he went missing, didn't Radha say that she didn't recognise it was KRK on the recent havan puja because she had taught RK all these prayers when he was growing up. So it's not so easy for Madhu to know the difference, even when she's suggested come on the bed he lets her down gently with an excuse. KRK can either do that or show anger and she keeps quiet because RK during her pregnancy and afterwards also had a lot of mood swings, and he would blow up in anger and all were even staying quiet when he is that angry.
