That was another one of the plot holes I didn't say and wanted others to find. MoA takes place right after SoN, so Percy by this point has spent about a days worth of time at Camp Jupiter, spent about 4 days with Reyna and Frank, and spent about 6 days on the quest. That is barely 2 weeks, and yet he knew the Romans for weeks?
