EDWARD, Y U NO SPARKLE?
Edward went to Jacksonville, Florida with Bella. We never see him sparkle, not once. Yes he is indoors, but is clearly sitting in the sunlight.
Edward also went to Brazil - twice. We never see him sparkle there, either. To be fair the first time we see him in Brazil it is a night shot in New Moon. But still, what an odd choice of retreat for a guy whose biggest fear is being seen in the sunlight. No sparkling in Breaking Dawn, either.
My theory is that Edward’s sparkles are somehow tuned into the Seattle Space Needle and if he gets outside of a certain radius they stop working.
