It would make more sense if Dawn met Conner through school or a friend of a friend.And not knowing he was Angels son..As the episodes go one Dawn finds out Conner is adopted and Angel is his real Father ...That would be a shock to Buffy to find that Conner was Angels Son and he didnt tell her..And so she heads to LA to see him..And Angel would never believe Wolfram and Hart he would never make a deal like that,Cordelia would of brought him to his sences.. But it would of been a head turn for Angel to choose Cordy over Buffy.Because in a way I think buffy couldnt make up her mind about Angel,And kinda thought hed always be waiting for her...only to find he found love in some one else..And it to be Cordy...(What do you think)
