What happens if you say Caliborn's name? Does something happen?

When two cherubs still share a body saying the name of the one that is asleep forces the personalities to switch.  Like if you said Caliborn to Calliope back when they had the same body Calliope would go to sleep and Caliborn would wake up.  Calliope told Roxy her name because she feared Caliborn was up to something and would try to predominate (which he did)
