i dont think shalini iz the spy.....see my reasons -
raj took colonel's call in front of shalini....and the col. said that somebody was already in the trigger room and they were getting signals n so he asks raj to check up the trigger room...............aur agar wo spy trigger room me tha uss time .......then there's no question of shalini being the spy coz she was standing in front of raj that time n not in the trigger room.................right?????????
and also shalini is not so thin and tall like the figure that ws seen in the trigger room..............shalini is shorter than that
and i think its ritu coz she must have taken the swipe card from raj's pocket when she hugged him on monday's episode.............wat say?????????wat do u ppl think now???????
