>What do you do next?
Turn around and follow me back to my house.
>Also, who would you assume is the doppelganger? You or them?
I wouldn't assume. Each of us could be as legitimate as the other. I'd have to go confront me to find out.
Where it REALLY gets interesting is after that. Are we duplicates, mind, body, and memories all? If so it would be interesting to see if we would be inseperable best buddies since I can't stand anyone who isn't me aside from 2 other people in the world. Or would we be so identical we were actually incompatible and just pissed eachother off? The sexual possibilities are endless. I have a feeling we would become completely useless if we lived together, always wanting/expecting the other to do stuff.
Also, which one of us is new? Was the new person created in a lab and sent to infiltrate? Was the new person a duplicate existing in an alternate dimension that had the misfortune of falling through an interdimensional hole only to end up in my timeline, and therefore not "new" at all, just exactly duplicate and relocated? If one of us did prove to be a new imposter, rather than a genuine natural copy, and things between us grew awkward, I would definitely worry about the genuine one being killed and replaced by the infiltrator.
