I think it happened when they went back to their own enclosure. They were all angry or upset. I don't know how much you might know about a reyvateil, but in my case and in the case of I.PD's we're all connected at a subconscious level. We're flawed in the fact that when one or more has an extreme emotional outburst of anger or sadness, it causes one or more to have what we call an I.P.D outbreak. Mine was a positive reaction. They were angry or upset and it all overrode my own emotions.

If... that makes any sense. That's the best way to explain it.
