From yest episode when Shikhar was leaving RV and Ishani in Ritikha's room, he requested them to take good care of Ritikha. That gives some insight into the truth of Rithikha's baby. Is Shikhar only Chirag and this is his makeover which Ekta's does plastic surgery. I feel Shikhar is here to stay till the end along with Ritikha.
Shikhar is only appearing to support Ishani and a silent observer throughout.
He wants Ishani by hook or by crook. He knows Ishani wont budge from her position until she proves Ritikha guilty. He is now moving towards Ranveer as if he is in his support. From yest episode Shikhar has realized Ranveer is more focusd on his promise to Rithikha than his love for Ishani. So now Shikhar will get drunk and maybe blurt out a cooked up story which might be like this- Ishani is not suffering with ML. She has come to prove Ritikha guilty and separate RaRi. She has promised to come back to me but i dont think she will because i could see her love for you in her eyes.
The above statements might be in support of Ishveer love, but against Ranveer's promises made, which might trigger anger in Ranveer. Now Ranveer has to ponder over this and his previous night proximity to Ishani close to consummation and what is it about Rithikha that Ishani wants to bring in open. In yest DNA test Ritikha's behavior was fishy.
Ranveer's earlier experience will stand in good stead for him in analyzing the situation. Chirag was far a big manipulator. Now RV's character has to come to force and be watchful rather than
throw his anger upon Ishani. I think the next scene where he decides to stay apart from her in different room follows and maybe the previous night after his close to consummation track he goes out and accidentally meets Shikhar. He is left pondering after that and now decides only to watch the next move of Ishani and Ritikha, where Rithikha will get a chance to attack Ishani. I am sure Ishani might discuss with Shikhar about how their plans are failing and they are unable to prove Rithikha guilty and Ranveer might evesdrop their conversation. He can even stalk Ritikha's movements.
If he is sensible he should get Rithikha's phone calls list and what she has been doing. This is what I expect from the Ranveer they have shown from the very beginning.
Offlate CVs have not focused much on Ranveer. They should now gear up for that.
