Fawn's closest friends is Tinkerbell besides Periwinkle, Terence and Vidia
Fawn and Tinkerbell has a few things in common

and i know: Tinkerbell is the youngest of the 6 girls group but before tinkerbell was even born, fawn was the youngest of tink's group
they have almost the same length, they loves adventure, helps a friend in need, they do dangerous things (fawn with animals and Tinkerbell with Tinkering)
they both know what to do when it comes to resolves it, they are both understandable and reasonable.

besides Periwinkle and Terence, fawn is the only friend who spends the time with Tink in person (alone)
and they both loves keeping secrets (in Legend of the neverbeast fawn was keeping secrets from the Hawks, and Tinkerbell is secretable, mostly seen in Secret of the wings and, The lost Treasure)
