She then explains how she knows and Craig knows immediately that Jennifer's baby is hers. Katie went on to tell him about her conversation with Jennifer's doctor. Henry arrives with the champagne, but Craig doesn't want it - he leaves to inform Jennifer that the baby is his and she and Mike cannot "steal" his child. Katie explains to Henry how Craig found out. Henry is really angry but Katie doesn't understand why. "It was partially an accident," she says. She doesn't understand when Henry says she wanted Craig to find out.

They get on the plane to fly back to Oakdale, and Craig tells Katie that it was no accident that she told him about the baby and that she should stop pretending to be regretful. Mike continues to tell Jennifer that nothing should change, that they can still get married and put Mike's name on the birth certificate, but Jennifer insists that getting married now would be a mistake. She urges Mike to walk away now, while he still has a chance. Instead, Mike tells her to stay at the chapel while he goes out for a while; he returns later, saying he's checked them out of the hotel and changed their flight back to Oakdale, and Jennifer says that should be his last act as her personal protector.
