Emily has been doing the “everyone’s paying attention to Sis” kind of thing all daynight, but has mostly been chill about her elfriends and her sister all hanging out together.
But this last time, she’s got an expression on her face that seems to be worrying about some other, greater danger to her sister being in Elf World for too long. Something greater than the “Sigh, roll my eyes, and chuckle at the antics” attitude she’s had all episode.
Em knows all about this world and how it works, even though we/Sis do not. We know she’s been going to and from Elf World for some time– she’s an old pro at this. Before she hopped in the portal, she was dressed like she was headed to the mall, not a fantastical alternate dimension.
There’s no danger to speak of– or at least none we’ve seen so far that would limit the time she spends there– so I wonder why that is.
