Discontinuity

Did touching the wrench to the edge of the time bubble melt it? Is your other self moving inside, or just standing still? If he's moving, maybe we can collaborate with our past selves if we anticipate our future actions! If not, then there's not much you can do about it; for all you know that's just the after-image caught in the event horizon of a black hole or something. Give us a quick lookaround: where are the exits, what do you have on you, do you have any useful information about what just happened, stuff like that.
