1. Ragini's mobile was conveniently left a few feet from where she was tied up so that she could reach it easily.
2. When somebody kidnaps a person, they make sure that they have no chance to escape. Yet instead of tying her hands behind her back, her hands were tied in the front and a few tugs easily opened the ropes.
3. The kidnapper (whether it's a male or female is yet to be determined) let their hair, wig or real, fall loose for quite some time to let Ragini jump to the conclusion that it might be Swara's hair.
4. As shown in the precap, that red shawl will magically be found in Swara's room.
Now all these clues lead to one conclusion. Swara is being framed. All means of escape for Ragini were right there in front of her which means that someone wanted her to run away and babble to her family that Swara kidnapped her. It could be that I am wrong and Swara has indeed kidnapped Ragini. But why would she leave behind so many clues when she knows that the first person to get under suspicion would her?
Only 2 people come to mind who could be the real culprits. It's either Uttara, as per some spoilers. It is still to be determined what kind of a character she truly is. And her sudden comeback seems pointless unless she has some ulterior motives. She probably wants to get rid of both the sisters, haven't figured out why yet. So she cooked up this entire plan to kidnap Ragini and make it look like Swara is behind it all. Killing two birds with one stone perhaps? Or it's Ragini herself who is behind all this. No need to guess why she'd want to frame Swara. What I found weird was that if she had money in her phone, why did she have to borrow some from that shopkeeper to make a call at home when she easily called her father before fainting? AP is already tangled up in her web of innocence so it wouldn't take much effort on her part to convince her that Swara is the culprit. But that shawl ending up in Swara's cupboard means that she has someone on the inside who's helping her. I have my doubts on Dadi too. She has always been very close to Ragini and has helped her out numerous times in her vile plans against Swara and Shomi. Not to mention Alka Kaushal almost always plays negative roles so I wouldn't be surprised if she ends up being Ragini's partner in crime.
Another scenario which is entirely possible could also be that either of the brothers is behind it since we saw the kidnapper wearing a mouli. It could most definitely be Sanskaar since the shawl was found in his room, though it would be an incredibly lame move on the CVs part to show Sanskaar in that light unless Swara is in on it with him. Or it's Lakshya and he's trying to frame Sanskaar. I am more inclined towards someone trying to frame Swara though. But who knows.
Some of the clues also look more like bloopers, hence the confusion as to who is really behind all this. Honestly, at this point, it seems as if anyone could have done it. God help us all for continuing to watch this show. My loyalty to Sanskaar is going to be the death of me one day!
