William and Margaret

William and Margaret are trees in the front yard of the NFC East family's house. They are most likely not sentient beings, but Wildflower hangs out with them and talks to them as if they are able to listen.

Appearance
William is a fully-grown deciduous tree. Since all his major appearances in the NFC/AFC East Saga take place in late fall and winter, he usually appears without any leaves. However, he grows leaves in spring and summer.

Margaret is currently a stump. It's unclear when or why she was cut down.

History
In Week 13 of the NFC/AFC East Saga, Bruce walks outside to find Wildflower sitting in William's branches. Bruce and Wildflower hold a conversation about the current NFL season, Joe's death, and the fight over the NFC East crown, which ends with Wildflower singing "Don't Fear the Reaper".

In Week 16, the episode begins as Wildflower talks to William. He laments over quarterback issues and the possibility of not winning the NFC East. Margaret is also addressed by name and shown on-camera for the first time ever.

In Week 17, Gus trips over Margaret as he is being chased by Wildflower. Gus hurts his ankle and is unable to stand or run. Wildflower takes the opportunity to run Gus over with a lawnmower, killing him. A day later, Wildflower reveals that he plans to watch the movie "Roots" with William and Margaret, but is unaware what the movie is actually about.

Trivia

 * William and Margaret represent the burial spots, and share the names, of the NFC East brothers' biological parents. They were both killed and buried by Wildflower after leaving to search for Bruce, who had recently gone missing.
 * The human William and Margaret were Cowboys fans, and thus treated Gus as the favorite child.
