How did Abba Saheb recognize Gauri?

While seeing the epi the thing which came in my mind was how did Abba Saheb recognize Gauri? 😕 I mean he have seen her 20 years back! When she was a child and now she is grown up!

Same question arised in my mind too? Things are getting confusing. And missing mohit too.

yaar.Yeh modern times hain.They must be seen each other pic.samne sayeed aaj pehli baar aaya hain.

I had the same question... i swear its just not possible to even recorgnize her so quickly even if he had seen her pic... Insaan thoda toh sochega na ke yeh ladki ko kahin dekha hai... this is weird that everyone recognized her... STRANGE!!!
