Having just so many emotions over this exchange because

• if the Eridians don’t know about radiation and this is a surprise for a ‘space-faring race’, they possibly became space faring for the first time for this mission
• their sleep is very variable so Rocky possibly couldn’t tell if they were asleep or dead until at least twelve hours had passed for each of them
• and then just the general them getting sick and Rocky not being able to help or fix them because they didn’t know!!
