I also find it interesting how Dru persistently refers to Angelus and Darla as "Daddy" and "Grandmummy" denoting the family line, but never refers to Spike as her "son". In "Lies my parents told me" she has the line "I'm the other who gave birth to your son" eg she sired Spike and brought him into the vampire world, but she never claims ownership of him as her son which seems odd as she keeps to the family names for Angelus and Darla. This could suggest that she instantly viewed Spike as a lover and partner rather than the next "generation" in the family line.
Spuffy was good when it was played for laughs such as in "Something blue" but I would've rather Spike and Dru stayed together as well. I think Spike does still have strong feelings for Dru, if she ever found her self in trouble, he would ride to her rescue even if they weren't romantically entangled..
I intend to post it on here when it's finished, it still a work in process though and I don't want to rush it so it could be a while.
Agreed. I also think that perhaps that is why Spike was able to adapt to having a soul easier than Angel did. Spike was only in it for "the rush" so nothing he did was ever personal whereas Angelus focussed on the victims because he considered what he did as an "art".
