This is how it can happen! RL is visiting Dhani in AN. Dhani is not home but DT lets a wait in ViDha's room, assuming they are sharing a room against KT's consent. It is dark with candles and RL thinks Viplav wanted a romantic time with Dhani. However, it is Raja who organized it and was waiting for Dhani in the room. Remember, room is dark so both cannot see each other until after the attack. RL gets hurt but not raped because just then both hear someone is coming! Could be Dhani,Viplav, or both!
Raja will hide. If Dhani comes alone, suspense could be who did this to RL. Viplav could be a suspect for an episode or two, but will be cleared somehow. If Viplav or both come into the room, Viplav is definitely not a suspect and he promises to get justice for RL right then and there! Except the usually strong RL is scared of getting killed or having her friends killed, because Raja threatens her not to mention society norms It is up to ViDha to motivate her and fight Raja!
