Hi, Deb. Here's a few easy ones off the top of my 
head:

Julia: Probably Session 25, but could be at the 
beginning Session 26. I'm sure someone here knows 
for sure. ^_^;

Spike with rife: Session 26 without a doubt. 
Right after Annie dies.

Faye doing her Rock imitation ("Do you smell what 
Faye is cookin'?" Sorry, I couldn't resist. ^_^): 
Session 15, end of the episode. Faye cocks her 
eyebrow as she stares at old flame Witney behind 
bars.

Hope this helps!
