Answer: Gia had flipped a canoe over while she and her brother were on a trip, perhaps intentionally.

It is stated in the passage that Gia was happily playing in the water next to an upside down canoe, and that he brother was glaring at her. This shows that he believes the incident to be her fault. The fact that the lunches couldn’t be found provide further evidence that it was unexpected, and that they had been out longer than just a joyride.
