Hmm, I don't think the stuff in the bottom panel is our tank; probably just Silent World junk. The last time we saw the tank was p494, and they're heading in the opposite direction (so - forward).

I'm not quite sure how fast that tank moves, but hopefully it's close enough that these three can catch up once they get free of these creepies, because Sigrun is going to need to be someplace warm ASAP. It doesn't seem to me like that much time has passed since it left, so it's possible.
