ritu -character analysis!

well ritu's character is going to change the whole track of lrl just as shweta had mentioned in one of her interviews.
she is being portrayed as a negative character. if she really loved navin she would have helped him out. but she didn't and neither did she help naina.
she wants to use raj for some reason just the way she used naveen and that's why she tried to break up the rn relnship.
she accused naina of hiding her past. she herself is carrying such a big secret with her and fooling everyone all the time. if naveen really loved her why didn't she accept him? what is the point in asking naina to accept huda's love when ritu herself rejected someone who loved her very much?
why is desperate to have raj when she knows that raj doesn't love her at all.
raj had come on the same mission for which naveen was posted at kma- to protect the nuclear triggers and catch the spy.
according to raj when naveen was arrested they found one trigger in his bag. there were two triggers. where did the second one disappear? did ritu steal it?
is she the spy?
how come she managed to do all that acrobatics during the dangerous exercise?
does she have any military training?
she certainly didn't seem lovestruck in todays's episode during the hotel date scene. she seemed to be wearing some kind of triumphant, mysterious look.
what is she? who is she? where did she come from?
why is she at kma?
her behaviour certainly raises some questions in my mind.

any one willing to answer or give their opinion on these questions?
kindly do so. i will enjoy reading them.
