I'm all over the place with this one, so many episodes that I really love, like Innocence, What's My Line Parts 1&2, IOHEFY, and Band Candy. And I love the entire Angelus arc so much. At the moment I think I'll go with...
School Hard - One of those rare episodes that make great use of every single character, even some minor ones like Snyder and Sheila, introduces an awesome new villain (or villains, since Dru) and has a fun setting with everyone stuck in the school, being hunted by vampires.
Bewitched, Bothered & Bewildered - It's fun, touching, and brings one of my favorite couples back together in a better way than before.
Also my favourite series/season of BTVS and then it has my favourite finale, favourite 2 parter (Becoming pt 1 & 2 followed closely by my 2nd favourite Surprise/Innocence), favourite BTVS episode (again Becoming pt 2), favourite series/season arc, favourite villain (Angel/us).
Yeah my love for the 2nd series is endless...
1) Becoming pt 2
1. Passion, because it broke me and I like that sorta thing
2. Becoming part 2, probably not for the same reasons as most people because I was never that in to Bangel although it's still an amazing scene - mostly it is for the Spike and Buffy, Spike and Joyce, torture my favourite character why don't you, is my head big?
3. Dark Age, because I'm a sucker for dark pasts coming back to bite people in the arse, and, yeah, favourite character so...
1. Lie to Me because of the famous quote that defined the rest of the series. Also, Ford was an underused sympathetic villain.
2. Passion was painful to watch, the ending. Same reason as Rachael why this lands on my favorite. Also see my custom title.
3. Becoming Part 2 because of the same reason as most people, Bangel, and also how heartbreaking the ending is (see my custom title again), and also because Buffy finally embraces what a Slayer's strength really means, and not just her physicality but also her willpower to endure the nightmares to come. She still has a long way to go before Restless in season 4, but this was the start of her maturity.
Also, did I mention that ending? lol Seriously, "Close Your Eyes" just never sounded the same again after this episode, both the soundtrack and the phrase. There are better episodes down the road that better define Bangel's tragedy since Buffy was only forced to kill Angel because the fate of the entire world was on the line, but this episode was probably the most heartbreaking Bangel episode of all that poignantly describes the fate of a hero in the Whedonverse. Happiness is hard to come by.
"People love a happy ending. So every episode, I will explain once again that I don't like people. And then Mal will shoot someone. Someone we like. And their puppy."
- Joss Whedon
Honestly, there's so much to unpack about Becoming Part 2 that I regret not joining the site earlier while I was watching the episode. I would've had a lot to talk about.
Honorable mentions go to "What's My Line", both parts (but particularly part 2), simply because of my love for Kendra. Killed By Death deserves a mention too for having one of the scariest Buffy villains prior to Hush.
Innocence - How do you react when you know something you have done has caused harm to other people?
Bewitched, Bothered and Bewildered - Great fun and a good representation of a glamour gone wrong.
I Only Have Eyes for You - Haunting (literally) and a lesson for Buffy that having no compassion may make you into a monster and an ingenious twist on the original story in that when Angel went over the railing, he could not die, so they managed to end the curse.
Halloween: Another reality alteration episode. I like Willow's arc in this episode the most. Bewitched, Bothered & Bewildered: Hilarious. Also, I like Xandelia. More shallowly, I really like Cordelia's outfits in this episode, too. Becoming Pt. 2: Best season finale TT__TT
For some reason, I seem to like Inca Mummy Girl, too. I blame it on Oz's first appearance and his first reaction to Willow. 😇
I chose Halloween, Bewitched, Bothered & Bewildered and Becoming Pt. 2.
