In fact, even though as a Changeling Fracyal can be quite recognizable, he has already a way of being a little more out-standing in a way it would become difficult to pinpoint his face again (or the face of any human being in his place, that is). He has a nice set of Nanotattoos, which he uses in a "my body is my canvas" sort of way. So, he may be almost invisible (well, if he had a chameleon suit, which he doens't, or when he is naked, which he won't [since it's not very smart to infiltrate someplace without at least some armor]), but mosty importantly, he can make his skin bear tattoos so impressive looking and that cover so much of his real features that being recognizable would not be a problem.
about the interrogation thing, Fractal would prefer not to kidnap someone, but to fool the person. He is not a good interrogator, but he knows how to fast-talk someone or make the one feels safe to tell things. Something more in the line "my work is a piece of crap, I spent all day long cleaning the mess my superiors do. Don't you feel like that sometimes?" and so on...
And I still believe I can enter the facility with the guards permission, if I can just fool the guards enough that they don't have time to heck who Fractal really is or who sent him... In this case, then I would like to tase a guard out and pass myself as him, controlling the patrols inside as to get the others leeway on the place they are operating...
Answering Sentinemodo's question, the info we want to get from inside involves where could we find the security console, where or who the passcodes to the system can be obtained, if the info we already have is true... things that probably can only be discovered from someone who works there.
And I really liked the bird smashed to the camera idea...
