I really hope that if Vikrant does find out about Sarita and Raj 'running away', he doesn't take it as an angry, jealous husband. We know that he is going to be increasingly torn between his attraction/love/admiration/respect for Sarita and his feelings of guilt for "forcing" her to marry him. That's what his self-thoughts seemed to reflect.
A little bit of caring from her is 'melting him', because he's been without comfort/care for a long time, fighting against the world for himself and his son and having no one but himself to count on. His loss of esteem in the pre-cap at being an unsuccessful father is hard to watch, and Sarita is the perfect person to boost his and Abhi's morale.
The more he tries to distance himself, the harder he finds it to stay away from her. I actually think that the fact that he was sleeping on the couch without them having had a fight was telling of his condition and he actually gave away the fact that she was getting to him. When they ended up sleeping on the bed, he seemed relieved but also distraught.
When Vikrant is truly crazy about her, I want his discovery of the elopement plans to throw him off and make him introspect. Maybe even make him hate himself, be guilt-ridden, and want to let her go with her 'love' ... a la Hum Dil De Chuke Sanam. Yet, when Sarita decides not to, he won't believe she is doing this out of love, but out of compromise and a sense of duty towards Abhi and him.
After a while, I want Sarita to be falling in love with him, but Vikrant not taking notice or not reading much into it because he would attribute it to her friendly and caring nature. Just like in the pre-cap, she's doing this team-building thing to get them both to cheer up, because she is basically a caring person. It has nothing to do with love, but with co-parenting. These activities will bring them closer as friends and confidantes, because romance isn't sufficient to sustain a relationship like marriage. Eventually, when Sarita is in love with him, I would like to see him finding it hard to believe and keep thinking that she's labeling compromise as 'love' and that she doesn't love him. Her efforts to convince him should be interesting - knowing Sarita's cheekiness, she would probably add a twist to it!
It would be quite interesting to see the CVs take a different direction: not a physical separation, but a separation of hearts, and the anguish of living together physically but living apart emotionally.
