They should add an Edward-Adewale Assassin Mission.
The timeline would be a be finicky, and where something like this could be placed could be dicey.. but am I the only one who thinks there could be some really badass cinematography and artwork that could come of a mission that involves Edward and Adewale working together? Imagine the two of them, in their respective assassin outfits, back to back, Edward with a pistol in one hand and a cutlass or pistol sword in the other, then Adewale with his machete in one hand, and his blunderbuss in the other, both facing a surrounding group of troops.
I’m not sure where exactly Edward is during the time of Freedom Cry, but perhaps something like this would be best added to a hypothetical Freedom Cry: Resynched. Since the two are only full-fledged assassins at the same time, but that pojint in the overall timeline. Edward could appear near the end to help Adewale and acts as Adewale’s quartermaster or helmsman on the Experto Crede. A nice role reversal the two could have some quippy dialogue over. It would probably feel sort of shoe-horned, but it would make for some really badass photo-mode moments, and overall epic cinematic I bet!
