The Struggle of Parting Ways
Tails knew Sonic never cried, it just wasn't him, even if Tails had the chance to witness him tearing up once or twice in his short life, but never cried, his eyes shined sometimes, with emotions more than tears, but they never spell, they well up his eyes and steadily stay there until he blinks them away or they dry of sheer will and stubbornness, that was just his brother, that's how he handled his feelings.
Sonic never cries, and he didn't cry when they sat in silence on the floor in Tails's room, packing up the yellow bag that used to carry their whole life and everything to Sonic's name before they settled in the workshop, tails wasn't going to take it at first, he wanted to grow, he wanted to be his own person, he was taking the cyclone instead of the tornado, he wanted to feel like himself and grow into his full potential without any influence, even Sonic's, especially Sonic's
But the rational part of his brain told him that if anything was going to hold him back it certainly wouldn't be their bag, a piece of worn-out fabric, holding more memories than any other item they have now,
and maybe, just maybe a tiny part of his brain wanted it, wanted to have something of theirs, of sonics, to keep with him for reassurance, it was a childish part, a traitorous one, but his fight over it was weak.
When Sonic showed up at his door holding the bag in his hand and offering to help him pack up before his trip, tails couldn't say no, sonic smiled at him, one of his signature grins almost too natural for the situation,
He didn't cry when he stood in the hangar with a less wide smile but a smile nonetheless still planted in his face, quietly watching tails do the last of many checks on the cyclone and putting away all the things he needed.
There weren't many words to be said, they already had that talk, and soon, the quietness became too much to bear. He was too familiar with Sonic's behavior by now, and could always sense the unsaid words that Sonic struggled to voice or refused to say out loud. However, this time, he felt the weight of the unspoken words in the air around them, and for the first time in a while, he couldn't fill the gaps. He could feel Sonic's gaze on him, and he tried his best not to fidget under the intense scrutiny. When he finally mustered the courage to look up at him again, he found Sonic's arms open and his expression soft. too soft tails almost looked away, He hesitated for a few seconds but soon gave in when Sonic gestured for him to come closer.
Sonic didn't cry as he pulled Tails into the hug, not even when his arms tightened around him too much it was almost painful. He cradled the back of Tails' head with his palm, just like he used to do years ago. sonic remained silent as Tails buried his wet nose in his shoulder and cried, despite his best efforts.
He didn't cry sending him off, tails turned on the engine and nodded when Sonic gave him a thumbs up after checking the way in front of him, all clear.
Tails soared into the sky, he blamed the tears welling up in his eyes on the crisp morning air hitting his face too fast, the fact that his eyes got used to it long ago to tear up went ignored, and the fact that he was wearing his goggles completely forgotten, tails didn't want to look back, not now, not at the start of his own journey, not when he probably looked miserable and childish right now, not when that was exactly what he was trying to grow out of, but he couldn't fight the strong feeling that washed over him, forming a lump in his throat, a tiny voice in his head, sounding suspiciously like his younger self, told him that one last look at his brother won't hurt, one last glance for the road, for good luck, for extra comfort, for the cold nights, he turned.
And he saw him, still standing at the hanger door almost too far to see but Tail's trained eyes didn't miss the small shake in his shoulders, sonic was covering his eyes with his palm and his face was looking down, whether Sonic thought tails was too far away to see him anymore or if he just couldn't hold it any longer tails didn't know, but it was too much to witness.
so he looked back ahead trying and failing to swallow the lump away, he pretended that he didn't see anything and that his eyes were clear and not too blurry to see through, years of practice and the way ahead of him memorized like the back of his paw was the only thing keeping the plane airborne.
