From the moment that Sookie had explained the plan to him, Bill had found it to be an ill-conceived hair-brained scheme. Especially as it involved a werewolf, as he'd figured Max out to be. And yet he went along with it, almost inviting himself to be among their company, knowing he was virtually walking into enemy territory - Fangtasia was not exactly filled with his favorite vampires, especially Sheriff Eric Northman. Why? Because he wanted to be near Sookie. To have her, as much as he could, even if it was in the presence of others. To protect her as best he could because God only knew she had a penchant for getting herself into predicaments. Probably due, at least in part, to her fae blood.
He didn't see Eric's car immediately, and at first he was hopeful that perhaps the Sheriff was not in. But then he spotted it, and his hopes of avoiding the Norseman began to sink. Nonetheless, he was determined to see this through, at whatever cost.
"Stay close to us and listen to what we tell you to do," he fairly hissed at Max, giving him a glare that could only be described as intended to make him think twice before doing something stupid, then think again.
