Okay, now I'm gonna address something here. * Silver CAN'T be a Future Gray. As pointed out by others, that has flaws. HOWEVER, Time-travel or rather, Space-travel is still a possibility. What if its an "alternate Gray". No, I don't mean from a parallel universe with different laws. I mean a younger Gray who accidentally slipped between the fabric of reality and made it into the current time-space many many years ago. Or it doesn't even have to be like that. It could also be an older alternate Gray who appeared more recently. This would explain the difference in scar positions. Actually, you can take the "alternate" part anyway you want. As long as it doesn't step into "Edolas" territory that is. Edolas was messy. Also it was inconsistent. But that's understandable since Mashima wanted it to be like a joke.

Basically, think of it as something that has nothing to do with how Eclipse went. Eclipse had certain paths that were connected. Here, that is different.
