Everwood (2002)

Season 2: Episode 10

Horrified to discover that Ephram and Madison are involved, Dr. Brown stops short of firing her, but Madison decides to quit leaving the Browns to a very unhappy holiday, especially when Delia discovers another troubling relationship - between her father and Linda Abbott. Stressed by Thanksgiving with his cantankerous mother-in-law (guest star Betty White), Dr. Abbott reacts badly when Amy brings Tommy (Paul Wasilewski) to Thanksgiving dinner. Finally pushed to the breaking point, Amy runs away from home.
