Wyll's banter has some serious timing issues. I got the rat comment shortly after we had our run in with Gandrel and he suggested Gale could pick up a new monicker "Master of the Weave" basically two steps after Gale confessed his whole story. I am sure it wasn't intended this way, but the timing made it feel cruel. The exchange he has with Lae'zel about whether she has ever done a good deed also feels like he is making fun of her, because she doesn't understand the concept.
