You don't read the Buffyverse comics, or you just don't know about the IDW ones? Well, IDW Publishing is the comics publisher that used to have the right to the comics adaptations and continuations of "Angel", while Dark Horse had (and still has) the right to "Buffy". Dark Horse only finally acquired the rights to "Angel" characters this year, so Angel now has his title, which he shares with Faith, under the Dark Horse season 9 roof, and AtS-specific characters like Illyria or Connor are supposed to appear in the new season. Under the old rules, Spike was one of the IDW characters and appeared in their comics - they released a lot of Spike mini series, in addition to his appearances in the main titles like "Angel: After the Fall" and others under the name of "Angel" as well mini-series under the name of "Illyria", for instance. he last Spike comic was an 8-issue comic called "Spike", written by Brian Lynch. Brian Lynch is the main IDW Buffyverse writer, who wrote most of "Angel: After the Fall" and "Spike: After the Fall", direct continuation of "Not Fade Away", which was based on Joss's basic outline - but other than that, didn't follow his ideas too closely. "After the Fall" is usually considered canon but has never been confirmed as such, and most of IDW's comics are in the "murky canon" territory: Joss won't say either way, that they're canon or that they're not, probably because he is trying to be nice to the IDW colleagues, whatever he may think of their ideas. Calling the new series "Angel & Faith" was a perfect solution to avoid calling it either "Angel season 6" and de-canonizing the IDW comics, or "Angel season 7" and canonizing them.
