User blog comment:Darkcloud1111/''The Mark of Athena'' Plot Holes/@comment-4515675-20121021160447

Not exactly a plot hole but more something that bothered me and amused me at the same time. Can we take a moment to appreciate that Leo only made 7 rooms on the Argo II yet made sure to give the pegasi a whole stable? If Annabeth and Percy wouldn't have fallen into Tartarus then Nico would have slept in the stables because obviously the possibility of more than seven demigods aboard the Argo II never crossed Leo's mind. Also, they have wii, play station and a scenery panel that shows life footage from CHB but they have only one bathroom for 7 demigods and a crazy goat man. Imagine two ppl having to use the toilet at the same time. It would be enough to start another war.

This also pretty much crushes any hope we had of CHB and CJ uniting to defeat Gaea cause if the last battle happens in Greece the two camps have no way of getting there and Leo made it clear that he was going to defeat Gaea's army by adding new toys on the Argo II (yet they will still have just one bathroom).
