 the look on Buffy’s face when the Initiative soldier insults Spike (ep 13)

 Buffy’s grin of relief when she finds out Spike isn’t dead from either the chip or the monster who attacked him (ep 13)

 The way she asks him if he’s alright in that same scene, "Are you still with me?" Think about that wording and smile with me. (ep 13)

 The look of understanding between Willow and Buffy when Willow realizes Buffy can’t help her with her Warren problem because she needs to be there for Spike (ep 13)

 Buffy dressed in bra, talking to Spike about her date (ep 14)

— Buffy’s description of Spike’s crypt as "comfy" (ep 12)

 Spike flirting with Buffy after the "comfy" remark (ep 12)

 Giles’ statement that he can see what’s happening between Buffy and Spike (ep 14) Even the fact that he thinks it will cause her a lot of pain points up the idea that he can see how serious it’s getting between them.

 Wood’s disappointment when he sees the intimate look between Buffy and Spike and recognizes their attachment. (ep 14) He knows he’s lost...

 Spike’s offer to break up Buffy’s date, for the good of Xander, naturally. (ep 14)

 Spike’s game of "whose knife is bigger" with Wood. lol (ep 14) And we all know whose knife is bigger, now don’t we?

 Buffy’s overidentification with the student who is attracted to a boy who picks on her. And Buffy’s repeated line about it being over, stated in a way where you can tell she knows it isn’t over at all. (ep 12)

 when Willow questions Buffy about moving on with her life, Buffy immediately asks, "Does everyone in this house think I’m in love with Spike?" (ep 14) Now isn’t that funny... Willow never mentioned Spike or being in love—that was Buffy’s very telling overreaction to an innocent remark.
