Giving a slightly hysterical, overwhelmed laugh, Starscream curled his hand over Skyfire's, tilting his face into the familiar-unfamiliar fingers. "It's.. it's called 'crying', Skyfire. It's a human reaction." He pressed a fervent kiss to the other man's palm, and didn't even care that everything was strange, and their bodies weren't right, and he felt too much. None of that mattered.
He shifted closer, as if he could crawl into Skyfire's skin and never be parted from him again, arm nearly too tight around him, entire body shaking nearly as badly as Skyfire himself was.
"We're on Earth," he added, trying to find words to explain through his almost debilitating shock and relief. "You-- you went down, do you remember?" He pressed their brows together, moisture slick against his bond-mate's cold skin. "I couldn't find you.. I looked and looked, but I didn't have enough fuel left to find you and get us back to Cybertron--. I.." He should have stayed. He should have stayed, and he hadn't, and it had been something he'd always regretted afterwards. Even if he knew that he might never have found Skyfire again. "I returned to try to get help, but-- the war had broken out." He slid his arm up Skyfire's back, fingers lifting away to cup the bearded human face. "Primus, Skyfire-- it's been over a billion standard years."
Would-- Skyfire hate him for not returning? If he did.. that.. that was okay. Because Starscream hated himself enough for both of them.
