La Maquina's thoughts are her own, not necessarily mine.  That's the way she is with [i]everybody[/i], and how my writing sounds in her voice.  It's not meant to be aggression on my part, though it very much is aggression on [i]her[/i] part.  Ultron is not impressing her so far, no.  Heh, he's got plenty of opportunity to change that, though!
