What are their chief tension areas?
I'm not actually entirely sure what this means, come to think.
You can read his tension in a clenched jaw and a ramrod-straight spine, if that's what we mean. Also, because he has no brain-to-mouth filter, in the way he's probably spouting profanities at the source of his tension. And/or trying to challenge them to a duel.
If they had a choice, would they prefer a subway or a bus for public transportation?
Can they multi-task or must they focus on one subject at a time?
If your character was allowed to murder one person without any consequences, who would that person be and why?
Also answered. Jeez, multiples of five are popular.
Do they have any weird bedroom habits? Any unusual kinks?
Yep, you guessed it. Answered.
Finally; if your character was forced to eat one thing for the rest of their life, what would they choose and why?
Bacon. Because it's delicious.
