I completely skipped right over the question about Faith's interests in Buffy... oops!
Some people see Faith as being in love/lust with Buffy, particularly in this episode. What say you?
In love with Buffy? Nah. Some sort of possible lust thing going? I could sort of buy that. I don't know how aware Faith is of it, or how far she'd let things go, assuming Buffy of amenable, but yeah... I think Faith has a bit of lust-on for her sister Slayer.
