When we arrived at Saint John's, we learned that Michacl had gotten chest pains and passed out while he was practicing some dance routines at the Hideout. When he woke up, he called his friend and plastic surgeon, Dr. Steven Hoefflin, who rushed to his side. After detecting an irregular heartbeat, Hoeflin drove Michael immediately to Saint John's.
Only after it was determined that he was suffering from costo chondritis, a harmless inflammation of the ribs, was Michael allowed to leave."
