Virgil has a breakdown - or rather something close to it - an identity crisis! The kids are testing a new game called 'Trillin' when it all happenes. Alex, who hadn't known Virgil was 'floating around' reckons he might be a spy for a rival software company. Of course at the mention of that Virgil gets defensive and asks the kids to help him prove to Alex that he is NOT a spy. The real problems then begin because Virgil can't remember who exactly he is! All comes well when they discover that it was Alex herself who created Virgil - he just grew a bit with time.
