Why did he call him Ripper?

Season 2 Episode 8 — The Dark Age In this episode we learn about the dark side of Giles. In his youth — far from wearing tweed diapers Giles was a rebel. He didn’t want to be a watcher, he wanted to be a bad ass and so him and his other bad ass friends started to summon the demon Eyghon into themselves while they slept because it was a big high. Umm…. so, basically, they were drug addicts of a sort. It’s not like having Eyghon in them gave them power or anything, just a high.Anyway, present day, for some reason, Eyghon has managed to come back and is possessing and killing off (or rather, killing off and then possessing) all of Giles little clique. Eventually, the demon manages to spirit himself into Jenny Calender — who was knocked unconscious during a fight with the dead guy that was being possessed. You see, Eyghon can only possess people who are unconscious or dead.So the trick becomes how do they free Jenny Calender from a demon without killing her? And in this conundrum we learn a lot of things about Giles, about the power relationship between him and Buffy, and also we have, I believe, a masterful foreshadowing of the Angel turning evil arc.  Only this time instead of Buffy’s actions unintentionally turning Angel evil, Giles actions turn his love, Jenny, evil.  In this episode, instead of Angelus snapping Jenny’s neck, we have Angel wringing her throat to get the demon out of her.  And Angel reminds us, chillingly, that he’s got a demon inside him who has been waiting for a good fight. Giles remarks that this monster is different because he created it.   This realization gives him the perspective and compassion to understand Buffy’s plight only a few episode later when she unwittingly releases Angel’s soul and brings forth the evil Angelus.We also have a great instance of a very strong Willow stepping in to take Giles place — and also Buffy’s place — as someone who makes the plan, executes the plan, and is totally in charge.
