The reasons you gave in your other post make sense to you and me if I am being honest as to why someone would not call Buffy but they do not make sense when applied to Spike.
Well thanks for that! I even tried to make them amusing. As for Spike...
Every single thing we had seen of him do up to that point totally contradicted his choice to not contact her. Spike doesn't think like that, he just acts. He is "love's bitch" afterall, he doesn't care how pathetic he comes off ( and he really does come off pathetic at times), he would have moved mountains to see her.
Hmmmm. I think pre-soul Spike, sure. Slave to passion. Screw what others thought. Pathetic? Sure, Buffy doesn't have a whole lot of respect for that.
Afterward, not so much. In fact, he tended to shy away from contact - granted he was kinda loopy at the time and admits freely that he didn't want her to see him that way. He even *gasp* seemed to think things through a bit more after being not-so-loopy. Actually he was
too shy and Buffy calls him on it big-time - dude just can't win with her. So, he goes to get his coat and becomes something a bit more like he was, but with more rational thinking. He still needed to get his mojo back and enjoy the fight and the kill instead of just doing it out of loyalty to Buffy and the good fight. Balance Daniel-san. Balance.
I don't doubt that or a second but instead the writers decided to turn him into coward.. I know why they couldn't have had him go after her but they gave a God awful reason.
Well, since you did agree that the reasons were somewhat "sensible", it *was* really more a matter of circumstances.
Pre-soul Spike, yep, all done to impress the lady. There would have been no hesitation or embarrassment.
Impressing the lady, not so much in season 7. I can't think of much of anything he did outright in order to "impress".
Afterward (post-ghosty), I think he just tried to do the right thing even if he didn't know a whole lot about what that meant without Buffy as his guide - and something that needed to be fixed unless he wanted to be just a Buffy groupie instead of an equal. It wasn't until "Doyle" that he had some sort of focus - plus pissing in Angel's wheatabix was a breakfast he would love to serve the old sire.
Shortly after Andrew was the whole Fred/Illyria thing to complicate matters even more. If you think the Cavemen vs Astronauts was anything but a reflection of their views (Spike more instinct / Angel more reason) with a Buffy subtext then....
And in the end Angel and Spike came to something of an understanding between themselves - an agreement to disagree; or in other words a middle ground to the Cavemen vs Astronauts argument where both views had to change and meet in the middle. All in time for the "last good fight".
Except...
I think "coward" is too strong of a word. If "coward" is used on anyone it would be Angel, but even then perhaps too strong of a word.
