Bee was too wrapped up in himself (in a non-egotistical way) to give much attention or care to the awe-inspired, horrified, transfixed humans. Except for Mikaela, because she was the only thing that kept him grounded. He tried really hard to focus on her words, to not panic or run.
She was pulling on his arm thing before he could argue and he was having to use the long legs to walk, briskly. "Oh, hohoho, look at this, Mikaela Banes, I can walk! Like you! I can...well, of course I can walk, I walked in Autobot...form, only it feels so different like this. You walk fast Mikaela, where are we going? Do you live here now? It is noisy here!" Now that he had a voice, he would shut up. He liked how flesh on flesh felt, looking at their enclosed hands and even swinging them once or twice.
He listened very intently when she tried to explain he wasn't the only robot to go human, and it gave him hope that he wasn't so alone. Until she mentioned which robots and then he was reeling, backing away and shaking is head and feeling what must be anger. "You have made contact with the Decepticons?! Have they hurt you, Mikaela, are they here now? How is it..." Well...maybe in their newly foreign form...they weren't so Starscream and Skyfire-ish. Maybe they could...you know....bond together. Or something. He wasn't mad with her, because she hadn't done this. She didn't know why either and while it was frustrating, he still felt no ill feelings toward her.
