- People being in two places at one time...
- Does time go by in the present if Isabel is in 1616?
- If you change the past, does it change the present?
- Does time run in a line, or in a circle, or in a spiral?
- How do people travel across time?
So anyway I am really pleased that my time travel makes sense to James and that I didn't have to put in a Narnia wardrobe to get Isabel back to the past!
