Trivia: When Scott goes sub-atomic during the climax, pay close attention. For a very brief instant, there are a few flash-frames of a human figure, and a human silhouette can briefly be seen reflected on Scott's mask. It's very easy to miss the first time you watch the movie. These are indeed meant to be hints that Hank's wife Janet is still alive in the quantum realm.
