fac·sim·i·le
/fakˈsiməlē/
noun: facsimile; plural noun: facsimiles
1. An exact copy or reproduction with near or perfect likeness to the original.
Twilight wasn't necessarily the social type of mare. Wanting to reproduce without such unpleasant side effects as 'pregnancy' or 'coltfriends', she instead creates a hoof-built android to serve as a duplicate foal. Said creation begins to learn from his surroundings.
Perhaps a bit too much.
