What a ride!! I'm glad I was alone when I watched it because I was literally cheering and jeering at my screen the whole time! I was hesitant at first at the concept of DT's redemption, as she was one of my most hated characters, but they wrote it surprisingly well! The way they explained her bully-ish tendencies was more than believable; I caught myself actually feeling sorry for her! The actual redemption went against the stigma and presented itself slowly, rather than just saying, "Poof, she's good now!"
The CMC's dialogue was written very well; they didn't lie to DT because most of them already learned that that's a bad idea in a previous episode. Most of what they said was very appropriate for their situation, and I forgot for a good moment that it was all scripted!
All in all, it was a very good episode.
