Amitabh Bachchan will host a special episode of 'Kaun Banega Crorepati 15' featuring his grandson, Agastya Nanda. Agastya is known for his role in Zoya Akhtar's movie 'The Archies'. Suhana Khan and Khushi Kapoor, along with other co-actors from the film, will also be present in the upcoming episodes. The episode will showcase Amitabh Bachchan recalling the first time he held Agastya, while Agastya humorously requests simpler questions on KBC. The preview also reveals Agastya's influence on the Bachchan household and promises delightful banter with Suhana Khan and an introduction to Khushi Kapoor.
