Every time Sean will write down a location's name, he will then teleport away to that place, unless he is negating himself at the time. It wouldn't matter what he uses to write, as long as the writing is done, but at first the ability will be limited if there is a lack of traditional writing equipment at hand. It cannot be used without writing, and it cannot use writing to achieve anything else. It also cannot travel through time. Another person can only be taken if he or she is touching Sean at the time, and this will then happen automatically.
