Such a poorly researched script.
Its shown that Akbar's reign has just started towards the end of Season 1 and then in the last episode John proposes marriage to Margaret with Taj MAhal in the background.
JUST EXPLAIN HOW???
Even a kid would know that Shahjhan ,the son of Akbar built TAj MAhal for his wife.Hence Taj Mahal didn't exist during the early reign of Akbar.
No one expects an accurate history line in period drama as surely there has to be some room for creativity and fiction but such blunders.
You really can't mess up with the timeline of Taj Mahal!!!!
