"[Saint Anthony] said, in his solitude, he sometimes encountered devils who looked like angels, and other times he found angels who looked like devils. When asked how he could tell the difference, the saint said that you can only tell which is which by the way you feel after the creature has left your company."

And it is clear to Evan, now: the difference between what is and what has been done; the present and the past. He sees that what he does and who he is isn't based on the past unless he wants it to be... No. That is the past, which has been seen differently through many different eyes and has become hazy and unclear, like a pond when stirred with a stick. Only the present moment is clear and free from prejudice.
