Brooke and Haley's friendship was pretty random at the beginning of season 2. Considering season 1 ended with Brooke and Haley NOT really being "friends" nor did they ever talk/hang out and season 2 started with BH hanging out and Brooke throwing her a bachelorette party, it's pretty random to me. Aside from that, I do think that BH had a great build up.
@Hoops, you seem to really not understand the fact that Peyton isn't on the show or in the town anymore. I'm gonna assume that we didn't see Peyton comforting Haley because Hilarie, the actress that portrays Peyton, wasn't there nor will she ever be in OTH again. Obviously Brooke is going to be shown being concerned about Haley since she's still actually on the show. LOL
@katrina87, yeah, BH had that episode in season 1 but that was mainly building up PH's friendship. As I recall, Brooke mad a comment about how PH weren't going to be friends the next day or whatever. After that episode, Haley and Brooke never had any real interactions. And like I said, to me, it seems out of the blue because BH weren't necessarily friends when season 1 ended and when season 2 started which was like a few days after the season 1 finale, BH are automatically friends and hanging out? I personally don't buy it.
But with Quinn/Alex, they actually did hang out. Other than Quinn taking pictures of Alex for Clothes Over Bros, they spent time at the bachelorette party and it was shown that they bonded. BH, however, never really showed that they bonded from season 1 to 2.
