No new ones grow. George and Vladimir are gone. Think about it. Think about brain trauma victims. Sometimes, the brain compensates.
Unused portions kick on line.
Remember, we don't use most of the brain, less than half. I think we need to get George and Vladimir to a hospital, on IVs, so their bodies get some real nourishment. The way they're going now, the 'bots will have consumed the bodies before any memories can kick back on line. Let me call Loki, see if we can get them to go along. I don't think the risk of infection is that high.
