Actually, Ghatotkacha did grow up very rapidly - rakshashas were said to mature much faster. A few weeks after he was born, the Pandavas left Hidimbi in his care. It was then that he promised Bhima that he'd be there for him whenever Bhima thought of him. So yeah, if not his origin, he did mature as quickly as Dhrishtadyumna & Draupadi.Speaking of which, one thing I'll say for last night's episode - I congratulate ⭐️+ for actually showing Dhrishtadyumna being born ahead of her - I was afraid that they'd force Drupada to first accept Draupadi, and then only give him Dhrishtadyumna. Incidentally, was he also born w/ a kavacha, like Karna?
