Season 1 Episode 5- Never Kill A Boy On The First Date

Buffy want's one thing, a date with Owen. Giles becomes aware of a new threat called the Anointed One, an unknown vampire that will serve as the Master's secret weapon. Buffy arrives late for her date to find Owen dancing with Cordelia and goes home. Much to the glee of Xander.  Owen asks Buffy out again for that night, and both Willow and Xander help her to pick out her outfit. Xander tries to talk her out of anything that might be attractive but it doesn't work.
Meanwhile, there is a bus accident killing five people, and when Giles finds out heads over to the funeral home to try to stop the Anointed One from rising.  He ends up trapped, while Buffy is back at the Bronze on her date.  Cordelia and a few of her friends spot Buffy and Owen, trying to ruin the date but to no avail. Angel then shows up to warn Buffy about the Anointed One, and when he realizes she's on a date, we begin to see signs of jealousy from him. Willow and Xander arrive to get Buffy, and the three take off to rescue Giles. 
Only, before they realize it, Owen has followed them.  He thinks checking out the funeral home is a game and ends up getting hurt by one of the newly made vampires. Buffy fights with the vampire and kills it, thinking that the Anointed One has been stopped.
The next morning at school, Buffy sees Owen and he asks her out again, but it's not her he wants as much as the danger she brings. Turning him down, she realizes being a normal girl and the Slayer is not really an option.
We then see the Master talking to a little boy, who had been part of the bus accident. It's reveled that the little boy is in fact the Anointed One.

This sets up a few of the arches for the rest of both the season and the series.  One being the character of the Anointed One, who plays a major role over the rest of the season.  Another is the competition between Buffy and Cordelia throughout the series to the end of season 3. This is also the first real suggestion that Angel has some feelings for Buffy himself.
But I think the biggest bit of story arch that is set up in this episode is that Giles begins to be seen in a father figure role. His reaction to her dating Owen is much to be expected of a parent when their kid starts dating.

The last few episodes I've pinpointed the theme of jealousy, which plays a part here too. But this episode is about knowing when to go for the thing you want and when to hold back.
Buffy is disappointed to learn that Owen isn't what he appears at first, and that he's attracted to the danger of being with her. 
There is a scene near the beginning of the episode where the character talks about not getting out much and how he is drawn to the morbidness of Emily Dickinson, and then admits later that he gets a complete rush from sneaking around the funeral home. He ends up being this sort of closeted goth guy - adrenaline junkie. Buffy has to acknowledge that a guy like that is not the kind of guy she needs in her life. It also gives her some more perspective on her own life and the job she's meant to do.
