oh, i agree - he got the chip in his head, but they kept the 'basic' Spike in place -- and he moved into the 'scooby' world b/c they kept bringing him in --
sure - they had him tied up in "The Initiative" - but later they would come across him in an alley and ask him questions - the ep w/ Faith (forgot title, sorry); then Buffy always goes to him when she wants information - in 'Real Me' she wants to know where Harmony would be hiding, (that's the 1st time we see B go to the crypt and punch Spike for info); and she keeps going to him - when she's looking for Riley, when she wants to know how he killed the 2 slayers, when she wants someone to protect Dawn and her mother, when she wants someone to protect Dawn later, when she needs someone to get them out of Dodge, when she needs someone to help fight Glory -- the list goes on and on -- if they hadn't asked Spike for help, he probably would already be on the road to some big bad *get the slayer out of my way so i can be evil* plan - or he would have gotten staked / dusted / whatever --
he's always maintained that he's 'evil' - he doesn't say it as often as he did when he first got out of the Initiative, but he still makes sure everyone remembers -- and for the most part they do, but there are the occasional slips - then they remember again --
the Scoobies know he's 'bad' and most of them refuse to let Spike into the 'friend' circle - tho some will show smidges of compassion toward him -- ie: in "Forever" when he brought the flowers and Xander gave him the 3rd degree, and Willow pointed out that he didn't leave a card - kinda made Xander feel stupid, but i'm sure he maintained his *yeah, but Spike's still and evil vampire* - however, Willow, a little more compassionate - but that's her nature -
Dawn - i think she still thinks Spike is cool - but we don't know b/c the writers never tell us --
Tara - she's the one that confuses me - one day she hates Spike the next day, she's more indifferent, then in "Dead Things" she was kind of making an argument for him -- not really sure where she stands on the whole "Spike" thing --
Buffy - she's inconsistent in everything anyway - so why would she be consistent on this? she's always telling Spike that he can't love b/c he doesn't have a soul - well, that's not true - one doesn't need a soul to love - b/c technically - you love w/ your head -- (now we can get into the whole, 'vamps are dead and don't have brains' thing, but there has to be something making them move around - so, for the sake of argument) -- anyway - Spike loved Dru - so, why can't he love Buffy, except that she doesn't want him to? ah -- that's it --- she doesn't want him to, therefore he can't -- weird logic, huh? (and this is all just my interpretation)
okay - think i'll stop there for now ---
