In the trailer for season 2 you can see Mark telling the world to prepare for take over.
In the new clip that amazon posted today you see mark talking to cecil and he says “im not my father!” While ironically making a dent in the table.
My theory is that mark will do everything he can to not be like his father but will ultimately fail. At the end of the season (the clip from the trailer) he will try taking over the world and that’ll be the cliffhanger until season 3
Agreed, any theory can be proven/ disproven by reading the source material. Weather book,manga,comic. Changes may occur but usually not major ones.
