I loved all the Doctor Strange references in the finale - the portal of course but also that teleporting battle. It was very cool - as cool as movies even on TV budget.
I also loved the Avengers-like food eating post final battle moment.
But the best part was Daisy convincing Fitz not to make the same mistake she did at the end of last season. Not to torture himself for things he had no control over. Not to leave the team for their own good when they want him to say. Not to take all the blame for everything that happened. They all tell him they are stronger together and that they want to face the future together.
