http://dailysciencefiction.com/science-fiction/time-travel/sarah-pinsker/join-our-team-of-time-travel-professionals Ahha! very short story, illustrating what I think about time travel...same as Spike in Buffy said about magic, "There are always consequences." and from Warehouse 13: "There's always a downside." Because of course, without that tension, your story doesn't quite hold.
