I love how Spike's spontaneous desire to dance is an indication of his unwillingness to address the issues between the two of them.
And I love the fact that Buffy wants to be at his level when he proposes is demonstrative of the massive change in Buffy's perception of their relationship. Way to go her.
I also enjoyed the fact that Spike and Buffy seem to have switched roles from S6... it's novel to see her being astute and sympathetic, instead of demanding and narrow-minded.
OOh. Last bit: love the fact that Buffy's first priority is to tell her sister. Thanks for the update and hope you had a relaxing Easter.
