It becomes more and more realistic but I have to ask why the fuck is Zoro named Roronoa then and not hunted down by the WG since his resemblance to Ryuma is that obvious? Did Zoro just get adopted by some Vegapunk scientist lady we have not heard of thus far that took him away to Paradise? Did Imu have so much PTSD from Ryuma that they intentionally forgot his face? If Zoro IS a clone, there are a lot of questions along these lines that would need to be answered.
