It's Jack and Eddie. UTH tour guide pointed it out to us, 1888 being around the time Jack and Eddie were born. And that "an old rumor" may finally come to fruition next year (would not specify, even though the whole tour group understood what he meant). Aiello wanted to allude to it in some fashion. That's why they are in there. Tour guide also said the point of BC was to add and expand to the mythology of not just the Body Collectors (the Grand BC/Masque scene) but "some other elements as well".That supposed to be Eddie or Caretaker? With the eyes being different colors, I'd guess Eddie.
