Things I remember: Buffy breaks up with Riley, Riley starts to stalk Spike, Spike ends up needing Willow and Tara to do a kind of dis-invite spell for Riley because he tries to kill Spike and Spike can't defend himself.

I remember several scenes where Riley either hides outside Spike's crypt, once because Spike doesn't come home all night because he was with Buffy, and at one point Spike comes back to the crypt and realizes Riley had been there because he could still smell him. I think there's even a time where Riley sees Adam leave the Crypt.

Help?

Is it sweetprincipale's Uncontrollable series?

(I think the disinvite is the 'bar thy enemy' spell in the second of the series, Unmentionable, using Spike's human aura)

YES! Thank you!
