You’re thinking of when Juliet when to find medicine for Claire “at Ethan’s old drop point.” So I definitely think they left supplies for him to conveniently find to share. Between the idea that they were “helping” the survivors by supplying needed medicine and giving Ethan this very likely backstory it definitely humanizes the Others more for me. They seem so ominous when we don’t know what they are up to. And clearly they still aren’t the nicest folks around or they’d just invite them all over to the house. Haha. At least Ethan’s backstory explains his dedication to the job. lol
