+ Buffy inviting Giles Sr. (or whatever name you give him) to Sunnydale without telling Giles.
+ When Giles Sr. asks about Giles, have Buffy describe him in a way that says shes in love with him, even if she doesnt realize it, Giles Sr. does.
+ Giles finding out his dads in town, but not from Buffy or Giles Sr. (Could be one of the scoobies, cause, really, i dont know who else he'd find out from).
+ Naturally he gets angry at Buffy for not telling him. Make a reference to Buffy putting her stomppy foot down when it comes to Giles, and making the two Giles' speak.
+Make his father the good guy. Maybe Giles did or said something in the past that has amounted to years of guilt, which made Giles not talk to his father.
+A good makeup scene between Giles and his father.
+Giles Sr trying to convince Giles that Buffy loves him. (Maybe make a comparance to how he used to describe Giles mother).
+And of course, we can't forget the B/G smoochies. :-D
