A very good possibility that you have raised and they may just do that.
If they say that they put the money into his account because they found out what he did for Govindji's son, hopefully she will ask them after that why they didn't go to the police say they were mistaken he didn't steal the money so the complaint could be revoked. Since now Shivani has the proof that will free Raghu she knows that J was the one who wanted to file the case plus she sees the money in M's hand on the cctv hopefully she will put the two things together and realize what they were doing.
The way that they showed Shivani going to the bank to figure out who put the money in I never expected her to do that and it was a pleasant surprise. Her blinders are gone now and I'm hoping that she won't trust them so easily now. Raghu may not say anything of their past behaviors right now, but he may say something about the money and this time Shivani will support Raghu the evil trio will be shocked. I'm sure the CV's will do something that we didn't expect.
Tomorrow's episode will be worth watching.
