Sometimes I hyperfocus so hard on something, I forget I’m a person until someone interacts with me. I feel like some wild animal seeing a human being for the first time. I’m like “oh yeah I’m supposed to speak and stuff”
I would like to put down my argument that Vlad is wearing eyeliner, and this is not just tired eyes/eye-bags. This doesn't negate that he might have dark under-eyes as well, but this is definitely eyeliner.
Exhibit A:
The line around Vlad's eyes are thick and solid black.
We know for a fact that they can and will animate dark under-eyes, as we see with Danny in Control Freaks here:
See! That's not eyeliner, that is the tired eyes look. This is shading, rather than a thick solid line.
Freakshow clearly has eyeliner, and this is not a leap of judgment, seeing as he is explicitly goth.
So when you compare Freakshow's obviously meant to be eyeliner, and look at Vlad, it is very clear that he's wearing eyeliner.
Now his isn't as thick as Freakshow's and the thickness depends on the frame, but it's clearly thicker than other adult characters. See Maddie in this same scene:
So there. This is my submission. Vlad is an edgelord and he's wearing eyeliner and we love that for him.
