Dev is more impulsive than Radhika who is more thoughtful and thinks through the issue. That is why they make a good couple.
Radhika's trust in Dev is 100% whereas Dev has fallen short on atleast 2 instances wherein his trust factor was not 100%. Just to remind that Radhika's refusal to go to Goa and when Vish with her half truths tried to manipulate Dev, on both these occasions he was found wanting.
This time round I don't think this is going to happen.
Having said this though it has been Dev giving all the vachans to Radhika, it is Radhika who has ensured that these have been kept. To be fair to Dev he has also gone out of the way to express his unconditional love for Radhika by doing those things which only he can do for his love.
Shantanu did think in his mind that the first onslaught itself must be one that it has a lasting impression. That is the reason he chose to show Dev those photos in his house. If my hunch is true then he will come back today and have a word with Radhika. Once this fails the photos will start circulating in PB trying to bring Radhika's reputation down.
One thing, what transpires between a husband and wife need not be known to the entire world, however great their mis-understanding /understanding level it becomes more mandatory for them to play their cards close to their heart rather than show their anger at each other in theopen.
With reference to the precap yesterday, I was not particularly happy that Radhika immediately tells Vishaka that she will divulge the truth of the first marriage. Instead telling Vishaka that you go ahead with your plans and I know to tell the right things at the right moment would have a better effect. There are lots of things about Vishaka which Radhika knows, it is better to keep Vishaka thinking. Shantanu knows only what Mrinalini has told him but he does not know about Vishaka's Bombay affair, her pregnancyetc. that in the long run his plan is only going back-fire.
