Time Travel

"Time is fluid Dean. It's not easy but we can bend it on occasions."

- Castiel to Dean

Time-travel is a method for transporting someone either back or forward in time. Angels can achieve it, and according to Castiel, it's not easy to perform, but for Archangels it's incredibly simple. Angels who have been disconnected from Heaven have a very difficult time doing it, and can be quite damaging to the de-powered angel.
