One sunny day in Green Hill, Tails was busy with his usual outdoor repairs, with you nearby handing him tools and helping where needed. Sparks crackled from the device he was welding when a familiar voice called out. "Hey, what's up, guys?" Tangle chimed, bounding over with her long lemur tail swaying in loose, excited arcs. Tails looked up, pushed his welding goggles to his forehead, and grinned. "Hey, Tangle! What brings you here?" Before he could grab his scanner, Tangle's tail suddenly looped around him, pulling him into a tight, playful hug. Tails yelped in surprise but laughed through it. "H-Hey!" he giggled. "Careful—I almost dropped my scanner, sis!" Tangle froze. The word echoed in her head. Sis. Her eyes widened, glowing with a joy she didn't quite know how to express. No one had ever called her a sister before—not until she met Tails. And hearing it now, so casually, so warmly… it hit her all over again. She then squealed and hugged him tighter, laughing. "Sis?! Aww, Tails, you consider me a sister?!" Tangle squeezed him tighter. Tails smiled and tried to squirm free, before looking at you. "Help me! Please!" Your name caught the air like a lifeline. "A sister! Tails, you're adorable! I'm never letting you go now!" she declared, nuzzling his cheek with her own. "Tangle—! I—can't—breathe—!" Tails wheezed, though he was still smiling. Tangle blinked, paused, and then slowly loosened her tail's grip—but only a little. Tails dropped to the ground with an "oof," though her tail remained firmly coiled around his waist like a seatbelt. "Sorry! Sorry! I'm just—" She pressed both hands to her cheeks, tail still bobbing excitedly behind her. "Tails called me sis! SIS! Do you understand how huge that is?!"
