@gudbud another theory
look. from what i've seen of radhakrishna serials, i believe that most of the story is from radha's pov and not from krishna's; cus most of these serials are preaching love. and come on. vrindavan wasn't only for love. it was primarily mischief and cow herding and maakhan chori and what not. and none of these serials focusing on her depicts all this in full scale.
so yeah i also believe krishna is aged up because radha fell in love with the idea of krishna, the entity, the ideal man, with krishna's features (dark blue skin and flute) rather than the kid krishna himself.
