With every passing episode the character of Rajeev is turning out to be more and more attractive.
Despite the big storm over the MMS issue he never once raised his voice against Suman. Although he was upset over the issue he chose to remain silent in front of everybody and asked Suman in private as to why she did not confide in him. The manner in which he asked this was also gentle, more out of frustration at her failure to trust him rather than anger at her behaviour.
When he realised Suman had left the house he was worried about her well being. Still he did not let the entire household know about her disappearance. Even when his mother asked him about where she was he remained silent. He knew if he makes a hue and cry about it, matters will only get worse.
When his mom-in-law told him that Suman was safe and in her parental home he was relieved. He did not show any urgency to get her back because her mother told him that she wants to spend time there to relive her childhood memories. This shows that he respects Suman's wishes although, I am sure, he would have wanted to bring her right back.
When he realised that Suman could not have sent the messages he tried to find who the culprit was. One may argue as to why he did not try to do so in the beginning itself. But one must realise that he was in a state of shock- shock at first finding out about Tanu and second about finding out that his wife had kept back such a big secret from him. With such shocks one's brain becomes numb does'nt it? That is why he did not respond to Suman when she reached out to him the previous night. He was totally lost in his thoughts.
When his Nani ordered him to bring back Suman, he respected her wishes and rushed to get her back even though he knew Suman wanted to be left alone for sometime.
I tell you this guy is really something. If Suman cannot see his goodness and accept him as her husband she is a fool.
