Why did maniac bring mars bar to the east end?

Maniac brought Mars Bar to the East End to confront the tensions between the East Enders and the West Enders, as well as to show his solidarity with the East End kids. By bringing a gift, he aimed to bridge the divide and demonstrate that he could connect with both sides despite their rivalry. This act was also a way for Maniac to assert his place within the community and to challenge the prevailing attitudes of division and exclusion.
