I'm really glad you enjoyed Lorne and Caritas
Lorne is a Fav Angel Character of mine.
I side with Bob on Harmony...Mercedes is brilliant in the role.
Still nothing on Gunn-Why I wonder?
Miss Burkle is my Fav ......Going from Traumatised Fred to Strong empowered demon fighter and beyond is one of my fav Character arcs.
Darla & Dru + Flashbacks = Awesome......We find out Darla was given that name by The Master,that Angelus was a cocky enough to take Darla from the Master,that Darla was responsable for both the Gypsy Girl & Drusilla....yet took no blame,that the nameless girl she was befor Darla was a Prostitute,Angelus and Darla destroying the life of a man named Daniel Holtz.
The B story to BtVS 'Fool For Love' 'Darla' is a stand out ep from s2 for me.
Annie showing up not once but twice

I love that she made something of her life after meeting buffy in L.A.
I like the Pylean arc if only for the brilliance of Fred.(and the Joss cameo as Bob pointed out)
Notice Winifred went missing the year Joss&Co. filmed BtVS s1

Kate Lockley was never better then when she tried to kill herself(Reprise/Epiphany)..and I don't say that because I hate her but because of what we get from Angel being able to save her life.
Angel sleeping with Darla and lying to Cordy about it will seriously come back to bite them in the ass(I know you've seen 'Heartthrob',but Darla Preggo is the least of s3's troubles)
Can't wait for the s3 Synopsis...for the longest time s3 was my fav Season...it now ties with s2 just for the record.
