Episode 3 visually demonstrates several times that Seth's perception of the False Realm is strictly influenced by that of his current puppet, a concept that has persisted throughout HC1 and 2.
Episode 3 gives the player the choice to name the Puppeteer either Seth or Lilith. This can be perceived as an opportunity for the then-anonymous Seth to reclaim his name after Umbrella Man consumed it.
