SSEC scrapped sketch- Pre Meeting Miku: Page 4 (Patreon)

When Dusk is hysterical, or very scared, his eyes turn orange, thus is what the swirls represents, the red eye color and the yellow eye color swirling around and making the color. Also, Dusk is not Gay, per say. he is Pan, or Bi. I think Pan though, cause he frequently seriously dates plastic plants (cause he is lonely and cray, lol).
