I'm trying to remember what episode ended with three Datas. Each one had an object that had to be put in the correct spot. Each Data was actually part of a different time continuum I think, but only one of them was the right one to fix some sort of temporal anomaly that was emanating from the room they were in. They figured it out, the right one put the piece back into place and everything returned to normal. I think it was an experiment gone wrong or an attempt to improve the ship that lead to the problem. There is a lot I don't remember about this episode, and that makes it hard to figure out which one it was. The only thing I remember for sure was that it had three Datas that had to solve the problem at the end. What episode was this?
