Magnus was staying at CHB to visit Annabeth. He did not know that his cousin for got to mention that her boyfriend has a sister, a pranking sister. Bella smelled fresh meet as she planned her prank, though Annabeth warned her not to she did it anyway. I guess that is why Magnus woke up with Magenta hair, the same brand as the one Hermes used on Athena. I think Alex will like it though, how about you? Because, its never coming out.
