Bill appears to Vicki and warns her to get away before she's killed, but his thoughtfulness doesn't extend to unlocking the door for her.
I'd have thought he'd have let her out too, but maybe his ghostly essence doesn't afford him the human physical abilities he was capable of doing in life, even something so simple as unlocking and opening the door.
It was nice to see Burke and Sam friendly for a change, even if they were both drunk. For Sam it's the norm, but I think this is the first time on the show we've seen Burke 'potted' to use Carolyn's phrase for it. Of course Burke's good will to his former friend isn't going to last once he sobers up.
Speaking of Carolyn, she's back to daydreaming about Burke. Some might think she's justified because Joe elected to have dinner with Maggie rather than take her out, but Carolyn has been treating him awful lately, that I just can't be mad at Joe for wanting to dine with a mature woman at her house rather than be at the beck and call of an immature rich girl.
