1 — Melon was the only one who was emotionally and (partially) physically close to Legoshi when he got scales (we ignore the existence of scientists. To hell with them).
2 — Since Melon has been held in the facility with Legoshi since childhood, this means that he has not been able to get his tattoos and he most likely has not yet developed leopard spots... This means that in this fanfiction, when showing his leopard traits, Melon may indeed not be alone, he may have support in the person of Legoshi and Gosha.
3 — Legoshi and Melon coding-Ethel Cain
Melon being there for Legoshi when he got his scales and Legoshi being there for Melon when he got his leopard spots... that's so CUTE 🥺 It makes me sad to think Melon can't cover his spots because he hates them so much, but hopefully Legoshi can help him feel better? Though I imagine it's probably a bit of a challenge with Melon's trauma and all that...
