Krrish 3 Logic:

Krrish 3 logic:

Kaal (vivek oberoi) is made from rohit's (krrish's father) dna.

That's how he is krrish's brother.

And kaya (kangana ranaut) is made from kaal's and chameleon's dna.

So logically, she is kaal's daughter.

Kaya falls in love with krrish; but he is his chacha (paternal uncle)!
