And yet he still hasn't apparently done a DNA test...
Also in that one shot im2020 tony is old and Arno is young, while in this current time they appear to be close to the same age
Really hoping they reveal that Arno is some type of temporal anachronism, perhaps caused by when Franklin restored tony after crossing/reborn/return, and that Arno is perhaps a copy of evil tony from the crossing.
Or else that this Arno comes from an alternative time line and with the aid of future tech and th controller he brain twisted Howard and Maria Stark and programmed them with fake story about tony and then make a replica of the recorder or reprogrammed the recorder and made that giant armor with the intent to fail to keep tony distracted
Anything to cleanse the palate of Bendis tripe
