If the show had a European ending..
What would it be like?
Would Ted move to another European country or maybe even farther with no Tracy? Or accept Robin's child free life and eventually adopt assuming writers didn't refer to her as aunt Robin in earlier seasons? Or any other possibilities how he would have kids? Or maybe divorce from Tracy because she's not that perfect as he imagined?
Tracy being perfect and her death is just wrapping up the story and too convenient or smth, just doesn't feel realistic.
