the adventures of Spike teaching Dawn things he really shouldn't, but it coming in handy eventually for Buffy. Whatever you want to name it.

examples but not limited to:

lockpicking, bluffing, gambling, pickpocketing,the layout of the tunnels/sewers, fake crying, self defense, weapons stuff, demon customs.

of course Buffy starts out mad but realizes it's his way of taking care of Dawn when he's not there to help.
