Old Christine: Guess Who's Not Coming to Dinner?

SYNOPSIS

Somehow everyone Christine knows (except Lindsay and Marley) wind up going to Thanksgiving dinner at her parent's house. While Mom uses every subject brought up to mention Christine's status as a divorced woman, Matthew sees his teenage fantasy come true as Lucy sneaks into his room for sex. When Dad is a no show for dinner, Barb theorizes that he was killed by Christine and Matthew's mother, which neither of them can totally discount.
