If the First King of the Reiss family is also the 145th King of the Fritz family, that must mean the Reiss family is the true Fritz family while the newer Fritz family is some other family taking their place.

So if this is true, Dina Fritz could also be called Dina Reiss. This would mean Zeke is also part Reiss, meaning that if he gets the Coordinate, he can totally use it and become another Progenitor Titan. That might be a big part of Marley's plan. My theory is this: either they changed their last name as I already suggested (my first comment), or the Reisses stole the Coordinate from the Fritz family (it's possible that Reiss was the other Titan shifter that escaped from the Marleyans).
