@OldTreeCreeper The core kind of looks like the metal things on the side of Pathfinder’s head, but that’s about it. None of the other artifacts look like they’d be a head of a specialized MRVN unit, (except maybe the other twin core, which is similar to the one we discovered.)
It’s also somewhat unlikely that they can use this for combat purposes, since the first core is apparently really delicate, and if the casing is ever compromised, the inner workings would be destroyed. This wouldn’t be the best thing to use on a robot that you would use for fighting.
They’d still have to build many, many copies of the body of Forge, as well as somehow copy the artifact for each and every body.
Watson’s father’s death hasn’t really been addressed, but it’s not like they implied that her father died from an assassination or something.
