I think this is a clever gag that I haven't seen anyone else mention; Green attempts to reach both sides of the reactor hand keypads in two different episodes and is surprised that they can't do it. In hindsight, the impostor must not have realized that the crewmate hands don't reach that far(since they're not used to those kinds of small bodies with short "wingspans") while a normal crewmate would know their limits.

I think there's also a small scene of Green hitting their knee with a broom and getting hurt and it might be for a similar reason(their bodies might be surprisingly weak to the impostors)

Either way, the newly hatched impostors must have been trying out what does and doesn't work

In the Viper and Detective role trailers, they showed this place that seems to be different from all the other maps. When I first saw it, I thought that it might be lore-related but obviously the show wasn't out so we could just speculate. In the the tv show they actually tell us about the colonies and Industria. I think that the first image is actually either Industria or a similar colony where the crewmates might actually live.

I imagined it would be a floating city and they’d have some space elevator mechanism between the surface of the Earth and HQ.
