1) What type of personality are you?
ENTP, under the guise of an ISFJ.
2) How did you manage to escape? Planned, or on the spur?
You plan and watch and wait. Moment comes, go for it. Action, reaction. Time for each.
3) With help, or without? (Would it have been possible to escape alone?)
Perhaps not with the overt help; but occasional lapses, lulls in consciousness of the guards, misplaced trust which I'd have been cultivating for the last years, would help me.
Charm is a powerful weapon under the guise of meekness. That is the ENTP with the ISFJ shadow. The game of underestimation.
4) How would you escape out of the country, given the tight security?
Little details. There is always a way to game the system.
Or perhaps, a conspiracy. One is let loose to catch a bigger fish.
Edit: An underdeveloped ENTP cannot focus. But one who has developed his tiertiary Fe, and auxilliary Ti, would be be difficult to deal with.
