Would you be interested in official canon events that happened during the series' run but crossover between Buffy and Angel?
Piggybacking on someone else's post about whether or not Willow filled Buffy in in Season 7 before she went to go re-ensoul Angel and pick up Faith, I know we have the canon Buffy Season 8-12, the Angel and Angel & Faith, and other spinoff comics post series, but
would you be interested in canon comics or someother format that involved the Scooby Gang and Angel Investigations interacting in a crossover way during Buffy Seasons 4-7 and Angel Season 1-4? And possibly during Angel Season 5 (before the post-both series canon comics "officially" started)?
There's so much to work with -- there's no way that the Angel team wouldn't have let Buffy's crew know Cordelia passed away, for example. And they also knew Fred -- her passing, etc.
There's also multiple moments we are made aware that the gang knows each other (Willow saying "more like the call of Fred" when Wesley asks how Willow knew to head to LA to re-ensoul Angel, but of course we hadn't even seen them interact yet Willow and Fred knew each other).
