You are starting off on a trip (to where? for what purpose?) and need to prepare. Pop into a shop, ask someone for directions, stop for fuel, pack your bags, etc. How do you prepare for a trip?

You are stuck in a confined space - an elevator, a closet, a hallway with the doors locked, a subway car, a train, an island, a locked mansion - with someone who has wronged you and escaped justice, and whom likely will continue to do so. You have the opportunity to enact your own justice, though not necessarily the guarantee that you'll escape justice yourself if you do. The next few minutes are yours to decide. What do you do?
