Guys, some points to ponder!
After the flashbacks that DK had while he was telling Disha about his childhood and also showing his dad, they never showed Dhruv again!
Is it because the man is dead?
If he is, could it be that Gargi killed him (we know that she is capable of something like murder)?
Maybe as she killed him, Sumitra was witness to it and maybe seeing his blood, that is why she gets all hyperactive when she see the colour red!
And by witnessing this traumatic event, it could have put her in this catatonic state! And that is why Gargi does not want her to get better!
What do you guys think???
