Although I enjoyed the easy camaraderie of working together, I was waiting for the other shoe to drop. Spike's being all helpful and companionable, but he's still a kidnapping murderer. Xander's right to be wary, but he'll go mad if he dwells on what Spike's up to when he's out. There's nothing Xander can do but conform. It's classic Stockholm syndrome, and I wonder how long it will be before Xander stops checking in with Giles altogether.
