Sorry for not updating yesterday, but I was camping and didn't have any internet.
Connor should've known not to trust Travis. It was his birthday, and when Travis had suggested baking his younger brother a cake, Connor had thought nothing of it. He'd figured Travis was just trying to be nice, but had also forgotten the Most important rule do the Hermes cabin: 'trust no one.'
The "cake" Travis had made Connor turned out to not be a cake at all. But instead was a balloon filled with red paint, covered in chocolate icing.
Connor had decided to cut the cake with his favourite knife (he'd sanitized it, sort of), but that had been a huge mistake. The knife went through the icing as it normally would, but burst the balloon.
Frosting flew through the air, and most of it landed directly on Connor's face.
