As far as I’m concerned that last FitzSimmons scene was tantamount to a marriage proposal. My babies are getting married, the wedding will be Doctor Who themed. Daisy will be Maid of Honor, Mack will be Best Man and Coulson will officiate. There will be a Tardis wedding cake and we will get to see Melinda May do the electric slide at the reception. FitzSimmons will take an early retirement in Scotland and live the rest of their lives doing science in a cottage and having adorable babies. The End.
