Raj, revisited the scene. When they focused, first it was hand with ring and in the next scene other hand. I think having a ring will be a coincidence. I still feel they just wanted to show severity of damage to his physical state.
oh.lets see what they going to tell about past.
but vidiths faced looked like anger at rishi.-
but no guilt on rishis face-
when rishi and vidith came face to face.
