The worst part about Changing in the winter really was the standing around naked in the forest until it started. Nick always found that the agony of it was too distracting to feel cold once it did. He still didn't know why this couldn't have waited for some time a little warmer, but there he was, Changing just to appease his girlfriend and boyfriend. At least once it was over, he wouldn't feel the cold the same way anymore.
Shaking snow off his fur once he was Changed, he trotted back toward the house, right up behind Kate to nip playfully at her tail.
The best part of changing was playtime. Something they probably couldn't include Stiles in too much without putting him in danger.
