Quote:Wells/Zoom/Reverse Flash... built the particle accelerator and knowingly set it to fail so that Barry and others would become super powered.
I don't think we know for sure he purposely set the particle accelerator to fail. It depends on whether Wells is a native of our current time period or not. I think he may well be. After all, we don't know his origin. Maybe he traveled to the future from our current time period, then traveled back here again. If he's a native of our current time period, then what happened to the particle accelerator may have been the accident it appears to have been.
