Since Tyrant didn't get a series finale here is what I think happened---
The Caliphate and Abuddin armies destroy each other.
Molly (Jennifer Finnigan) dies in child birth
Leila (Moran Atias) is killed during the last year of the war
Bassam/Barry (Adam Rayner) takes his newborn and disappears into exile
Sammy (Noah Silver)-unable to walk he runs away (to a country that allows such relationships) with his professor, Haitham El-Amin (Raphael Acloque)
Daliyah (Melia Kreiling) becomes President of Abuddin and brings real peace to the Middle East
