Continued from my last post since I was interrupted by dinner:
Also, if they're more 'keeping others out' than keeping him in, might they let him go willingly? You know, like 'I want him to stay safe in here, but I'm not willing to hold him against his will'.
It isn't a case of 'I want him to stay safe in here', although explaining what it is a case of would give too much of the story away. Regardless, while the one who put the building on lock down is willing to let him out, and is in fact actively helping him escape, the people outside aren't and things wouldn't end well if they caught him.
Air Vent Escape does in fact work. There's a plethora of buildings where the HVAC systems are big enough for people to fit in. (I even used it recently despite my work being in The Future.* )
So it's not so much a Discredited Trope as one people don't like to accept without either sufficient coolness, or good reason. (Such as escaping pursuit or getting out of an elevator system.)
Noted. I'm not sure how big the vents in this place would be but the character is rather small and skinny.
just read the topic name, but I'd say they just look like they belong, forge some ID, and act natural. If it is high traffic, this is much easier, other wise, not so. Just have em' look like they belong and have a disguise and good faked ID, or steal someone's and carefully replace their pick on it, giving them correct information to get in, but with their pick. Unless finger prints or eye scans are needed... I don't know then.
Acting like they belong isn't an option since as already stated, it's rather obvious that they don't. A fake ID would probably be easy to make but given the circumstances it would beabout as much use as a chocolate teapot.
Does your character know that there are other people trying to sneak in? Because if he knows, and since the building is empty excepto for him, it's pretty simple to do.
Wait for people who are trying to break in to make a break through.
Use break through.
Yes, he knows that people are trying to get in, in fact that's why he's trying to get out. As I said above, getting caught probably wouldn't end well for him. Plus he's trying to sneak something else out with him. Also, I didn't say that the building was empty except for him, I said that he was the only human being in there.
