I thought they needed Seconds strings to time travel.

that might be for time travel in all dimensions at once as I doubt a Time Lord or some such from the Doctor Who universe/dimension needs Seconds strings to use the Time Vortex.

We had this huge discussion trying to hammer out the new time travel rules so that people couldn't keep going back Existence-wide after a certain event a while back. I don't remember much of it though but we just had a convo about the individual universe time-travel the other day so this is good timing.
