Yesterday epi Dr Rao shows Shiva Katherine is tracked by Interpol. They also have the video of Katherine meeting the evil gang. He tells Shiva he doesn't know whether Katherine is a Garud or enemy of Garud.
The fact that Dr Rao knows Katherine is with evil gang and yet she mixes with Brahma Nisth Panth and he only asks Charles to follow her and Shiva to keep an eye on her has made all my alert systems stand up and notice.
Dr Rao knows more about Katherine than he has let Shiva know. Evil gang does not know Dr Rao has this much info about Kat. Usually such a thing is possible only and only if Dr Rao has indeed planted her, with the evil gang. A secret only she and Dr Rao knows.
Dr Rao does not want anyone else to know of this secret because that will compromise Kat. Hence only an eye on Kat.
Yes Kat has to be observed because her help to Garudas will be done stealthily without they knowing she is helping them, because she always has to prove her loyalty to Greison. She has to create the deception of being with evil gang till the very end.
Kat is going to look like a traitor for Shiva that is for sure, but I feel something will happen to Dr Rao to which Kat will be seen responsible. But story will be different.
