Can Joe hold it together or will he fall apart?

Joe "was overwhelmed with emotions after talking with new contestant Serena Pitt. The two discussed his breakup from Long and Amabile later told the cameras while choking back tears, “My conversation with Serena P. was like talking to Kendall.

Joe and Serena's connection was instant and it would be silly to throw it away over something that already didn't work.

Wells Adams stated, “It worked for Joe last time, you know, he kind of fell for Kendall and yes, they had their ups and downs, but they were together post-show for a very long time,” The paradise bartender added, “The show doesn’t work for everybody, but for the select few, it’s really, really beautiful. And so I think my concern with Joe coming back on was, it’s hard to recreate something — like, will lightning strike twice?”
