The emotional scene you're talking about is probably the scene where the alien PK played by actor Aamir Khan finally finds his spaceship and leaves the earth. In this scene, PK Jaggu's friend (played by actress Anushka Sharma) helps him find his lost spacecraft by taking it to the government agency that confiscated it. When PK finally reaches the boat, he turns to Jaggu, thanks her for her help and friendship, and bids her farewell. When PK boarded his boat to leave, Jaggu got emotional and started crying. PK notices her tears and asks why is she crying.Jaggu replied, "Because you're going," and PK replied, "I'll always be here," pointing to his heart. This scene is a poignant moment in the film, as it highlights the deep bond that PK and Jaggu develop despite their very different backgrounds and experiences. It also expresses the idea that even when we have to say goodbye to people who are dear to us, the memories and feelings we share with them stay with us forever.
