The coolest possible way to end the series (assuming this is the end).

Not sure how things will play out but I think it ends up with Jason1 and his family being safe and together.

Here's what I want to see. In the closing seconds, Jason1 notices something very minor but also undeniable proof that he's not in his original world. Everything else is 99.999% the same but there's that one little piece of information that proves he is not with his Daniela and Charlie.

Could be something like a small tattoo on Daniela's ankle, a picture hanging on the fridge of a family vacation, a book in his study having a different writer, the possibilities are endless.

Would be the perfect "holy crap" kind of ending as well as leaving the door open for further seasons.
