Exactly what is gaya gonna expose to defame NiRaj?

As far as i remember, the cctv footage of that evening shows Nisha hovering around Viraj's half opened door, Ramesh-Nishu talking in mute - because cctv camera records only video not audio - Ramesh walking away, then Nisha going away when she trips that ornament, picks it up, in process her bag falls, so does the note, she picks her bag and runs to hide, Viru comes out, checks then goes inside & Nisha leaves. Daadji enters flat, Viru leaves and Daadji picks up the note and hands it to Viru and Viru rushes away. Thats all the footage and i'm sure there's no way the camera had captured whats written on the note. The emails. Viraj and a certain EmailwaliFemale had chatted together, starting with the mother's letter, they planned to meet, ewf didnt show up, they became friends, viru shared problems with her, named her Arti, told her that Ms Nisha had asked him smthing and didnt know how to answer, then for some reason arti had stopped writing, viru kept on questioning her,

Then they planned to meet for the last time, arti telling him that she wil show her true self and viru telling her to pick up some package from her post box. Thats it. There's nothing else. Viru hadnt emailed that he luved her nor was there any kind of clue to nisha being arti. Only viraj wud undrstand that nisha was arti bcause of the footage. So exactly wud Gaya gain by exposing the footage and emails? Public wont understand anything unless she explains which wud only lead her to her own demise. Viraj and Gangwals wil kill her if she does that. So exactly what is she gonna expose? Isnt it normal for a person to chat wid someone? Isnt it normal for Nisha to go to her mentor/partner Viraj b4 the competition?

. Only viraj wud undrstand that nisha was arti bcause of the footage.
Isn't that enough for viraj to get angry on nisha??? Maybe there is nothing much to expose but the way gaya will be exposing it might make a bad impact on viraj and in angriness he will burst out on nisha which will break her heart again..and by the time viraj realises his mistake kabir and nisha will become good friends...and the starts the game of jealousy and love triangle...wht say!!! 😉

Exactly that is soo unclear
