So, it's probable that there were survivors. If this ship landed, I'd guess that the position itself is new as well. My people excavate things like this, but even they aren't so deep. [They dig out cars for scrap metal, to be clear.]

There may be survivors somewhere, or they may have been rescued. Is it likely that most would be abandoned here? [Lexa has had to adjust a lot in the few short days since she woke up in that pod, but thankfully, she's already been taught about space travel.]
