Actually I think there was some kind of flirting here and there but not shown to us previously...in unseen when Tharshan and Liya was eating from same plate...Sandy was making fun..He told Sherin your plate is already with Tharshan and I don't want it when Sherin told Sandy to come eat from her plate. Also, in another unseen Sakshi was telling Sherin he is making eggs to everyone (I think he was making for mathu) and Sherin said i'm not the jealous type. I think it was in reference to Tharshan...as they were discussing how Tharshan and Liya are taking care of madhu..and that Fatima must have told them before leaving...Kavin was beside them listening to all this.
