yes, this is him from the explorer notes. if you need proof go read the aberration notes, towards the end you will see what happened. also, i don't think rockwell made reapers however as reapers are mentioned before he reaches his infused form. i'm not sure about the nameless, though since they bear a lot of resemblance to humans, however considering what it did to rockwell, i don't think they were injected, but could instead be distantly related to humans generally since they look very similar. i've also heard that they were there before the event even happened. i'm not sure though, i'll have to go re-read the explorer notes to see some things to see what nameless actually are.
