Mom

Trisha's mom, Quilla Anderson, is not really a good mom as Trisha puts it. She divorced her husband and is always fighting with her son, Trisha's brother. She was so busy fighting with her son that she didn't realize that Trisha went off the trail. Trisha's mom takes Trisha and her brother on adventures all the time this one just happened to be a hiking trip. Her mom is very over whelmed with the divorce and trying to make her kids happy.

Trisha's mom is always trying to take Trisha and her brother to places they don't want to go to. Usually her kids don't want to be there, so it ends up in a fight between Trisha's mom and her son. Even though Trisha and Pete never enjoy their "adventures," her mother keeps on taking them.
