I made a halfling and went back to the Arcane Tower to check the height.
The halfling was too short.
So then I used disguise self and went through every option. Basically, Lenore seems to be taller than a dwarf or halfling but shorter than every other choice I had available: elf, drow, half-elf, human, githyanki, tiefling.
I thought, maybe Lenore is usually sitting when she gets a hug, so I tried sitting on the stool. Can't talk while sitting on the stool, though. I automatically get up when I engage in dialogue.
So I tried climbing on a crate as a halfling. Game didn't recognize my artificial change in height, still said the interaction was meant for someone taller.
I don't know. I'm at a loss.
Maybe Lenore is of a unique race that's somewhere in between in height. Maybe Lenore is as tall as a halfling, but floats around a few inches off the ground?
Maybe the cut scene needs work and they decided the size difference made for a good excuse for it not looking right?
