He saw Viria's art!

Leo walked over to the Aphrodite cabine the minute when he was within a ten feet radius alarms went off.
"What the!" Leo exclaimed jumping.
The door banged open and out walked out two girls, Jenny and Haley. They saw Leo and scowled.
"Gods Leo go away!" Jenny said.
"What did I do? What if I was here to see Piper?" Leo asked.
