From a linear point of view, they will have either already met the past me, who is not so forgiving a being, and I will simply be confusing them or seeming like I'm trying to play a trick on them, or. It will be the other way around, where they meet me first only to later run into myself from the relatively recent past and realize he is much less... amenable to a less bloody end.
