1. After her wedding, Riddhima is wanting to, for the first time, take her relationship further. She gets sent where Armaan is.
2. Sid decides to patch things up with Riddhima, and arranges a romantic dinner for her. She gets sent to Lonavala where Mr. Armaan happened to be.
3. Karwa Chauth - Riddhima keeps a fast for sid, and has her eyes closed in front of the..uhh..channi? (srry - i'm not north indian and don't know what it's called). Armaan comes in front of her first. Yes, she sees Sid first, but it was Armaan who was there first.
4. Today, Riddhima and Armaan have both decide to move on. Based on the precap, she finally makes a proper romantic move towards Sid. Almost the entire audience population has accepted that A and R aren't gonna wind up together...and there's Armaan once again.
These are just a few examples, and I could probably come up with many more if I spend some time on it...but you get the idea. Why is it that Armaan and Ridz can never properly separate? Perhaps destiny?
P.S. - SR fans - I know you have a completely different interpretation on how destiny has impacted the characters of DMG, and I completely respect your views. I hope you'll respect mine too :)
