Visibly startled--he'd obviously expected her to help Skyfire and leave him to figure things out on his own--Starscream hesitated for only a moment before nodding, moving to help Skyfire into the truck and climbing in, himself. It felt.. bizarre, but he wasn't about to mention it. After all, he supposed it was normal for humans to travel this way. "Thank you," he said as Mikaela slid into the driver's seat, his hands still curled tightly with Skyfire's, knees against the other man's. "I don't understand how this has come to be, but--" He glanced at Skyfire, thumb stroking the side of the other man's palm fondly.
He appreciated the chance. No war, no Decepticons, no Autobots, no Megatron. At least, he didn't think any of the others were present. None that he was familiar with, anyway.
A frozen moment, and then Starscream was shifting the blanket around Skyfire's shoulders again, fingers delicate against slowly-drying curls and exploring the human face. Fragile---breakable, as all humans were. He was terrified that any shiver meant something horrible. Illness. Injury. Old age. All of those things could mean death for humans, and yet.. even a few short years with Skyfire were preferable to an eternity without him.
It had already been an eternity, and anyone could tell how completely shattered Starscream was. He wondered, a bit, whether he was still the same person Skyfire loved at his core. He was certainly no longer the passive scientist---indeed, there was a reason he was second in the Decepticon army only to Megatron.
He knew how to fight, and he knew how to kill, and he was good at it.
