Martina is a wealthy relative from Susan's side. She appears in Hard Luck.
She was having a buffet at a hotel when she saw more food on another side, so she went there but she didn't realize it was a full-length mirror, and crashed into it, which resulted in breaking a collarbone. She sued the hotel. Greg believes the Porsche at Gramma's house is hers.[1]
Trivia[]
- This is the second time breaking a collarbone is mentioned. The first is in Cabin Fever when Mr. Sparks breaks his collarbone. The third time was within a flashback in Diary of a Wimpy Kid: Double Down, when Gary Heffley was trying to cut a branch because it was obscuring his driveway, so he got on the tree and chops off the tree branch he was sitting on, causing him to break his collarbone.
