Comics have a problem, and that is continuity - the obsession with placing the characters in an existing world, where every event is marked in canon. You're supposed to believe that these weepy star boys of now are the same gung-ho super teens fighting space monsters in the '60s, and they've only aged perhaps five years.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
