Padmé... was not happy. In fact, she was quite likely the exact opposite of the definition of the word happy, at the moment. Although she was relieved that Luke seemed unharmed, which is perhaps what allowed her to keep herself in check. For the time being, at least.
"Well," she finally spoke in a voice that was far too quiet given the situation, "it's quite a good thing Aang was present, in that case." Dropping a fleeting kiss to Luke's forehead, she smiled against the warmth of his skin and drew back slightly.
"You have nothing to apologize for, Luke," she assured the boy in a gentle tone. She assumed he must have unintentionally used the Force, given both the description he gave for the events as well as his reaction. For not the first time, she felt a surge of what could almost be described as rage toward Owen, although she quickly forced the feeling away. She may not agree with the man's decision to scare the hell out of a small child for doing things which came naturally to him, but her anger would serve no purpose here.
"Why don't you go get yourself cleaned up?" she suggested after a brief pause, tousling Luke's hair in an affectionate manner. "Your father and I need to discuss a few things."
Then, only then, did she look to Anakin, her expression unreadable although her eyes clearly shone with obvious disappointment at what had transpired. The only thing keeping her from being outright livid, in fact, was the fleeting realization he'd mentioned Jaina's brother arriving here and being injured. And, unless she was hearing things, the boy was apparently named after him.
Although randomly appearing namesakes was not going to keep her opinion silent for long. Just until Luke was out of the room and not privy to the discussion.
