Day 2 Supernatural Challenge
Day 2 Favorite Episode: Hands down my favorite episode is NightShifter from Season 2, I had just main lined season 1 and the first half of season 2. NightShifter was maybe the second episode I watched live with the rest of fandom. I loved every minute of it, the ending is perfect. Closing the episode with Renegade by Styx . PERFECTION! I've honestly watched this episode at least 25 times.
Swan Song from Season 5 is a close second.
