The brush of his thumb over her knuckles was both comforting and strange at the same time. It was such an intimate gesture, such a very human thing to do, that for an instant it was easy for her to forget that he wasn't actually a human. Oh, he may be a human now, but he wasn't supposed to be one. He wasn't supposed to know how to offer comfort as one would.
Still, it brought a faint smile to her lips. She didn't comment on Sam understanding. She wasn't sure he would, and she didn't want to get her hopes up only to have them destroyed. She couldn't blame Sam if he never forgave her, though. She wasn't sure she could even forgive herself.
Refusing to dwell on it a moment longer, Mikaela instead tried to figure out how to explain to Bumblebee what being hungry felt like, for a human. Was his stomach growling? That tended to be a question that most people understood, yet she had a feeling it might puzzle him a bit.
Finally, she decided there was really only one way to find out. "Come on," she announced with a soft smile. "I need to get a few things at the store since I left my groceries on the street back there. We'll see if anything looks like something you might want to try." And with that, she led him back down the street at a more sedate pace. There was another grocery just up ahead. A smaller one, catering more to the locals and owned by a man who came into the shop where she worked.
"So, how does it feel?" she asked after a moment, glancing curiously at him. "Being human, I mean?" Mikaela, of course, couldn't wrap her mind around how different it must feel. But she'd yet to really find out how different it actually was. Starscream wasn't one to really talk about it and Skyfire would, but tended to have more questions of his own than answers.
Maybe, she thought, Bumblebee would be different in that aspect. He certainly didn't seem to mind talking now that he could without having to rely on the radio for communication.
