Timeline:
- Taiga implies that he's a criminal of some sort
- We all get suspicious, because at least some of us aren't shady at all
- Taiga goes "Oh well actually I'm not shady either, but I don't know any details."
i'm not a criminal, at least in my own eyes or role message, but i know exactly what i'm suspected of and why i'm here. taiga might not, rounding up suspected members of an underground isn't too strange and he could be a criminal but also town, babylon 5 allows for the 'innocent criminal' option as well as 'lawful stupid' and 'orange and blue morality' options.
that said he didn't really tell us anything and its hardly a hard story to make up. i also feel obliged to point out that the only 'underground' in b5 is one that smuggles rogue telepaths or the narn resistance momvement against the centauri, which explicitly hasn't started yet in the game. so if this is game inspired taiga either is lying, a rogue telepath, or involved with rogue telepaths.
i wouldn't mention that except that if the mod gave him an rm discussing his involvement in an 'underground railroad' rescuing telepaths from psi-corps' brutal control he wouldn't likely describe himself as a criminal.
