EXCLUSIVE: What it's like filming 'Bachelor in Paradise' post-scandal

Less than a week after production resumed on season four of Bachelor in Paradise, some cast members have already been sent home. This time, however, it's because they failed to find love.

Vinny Ventiera, Iggy Rodriguez and Alex Woytkiw took to social media on Thursday to document their trip back from Mexico, just days after expressing their excitement about returning to the show.

It's clear that a few things have changed since production resumed on Paradise, a source tells ET -- starting with romantic connections.

"Relationships that started to form in those first few days of original filming might be different now, or nonexistent -- and other cast members formed connections while filming stopped," the source revealed.

Production on season four of Paradise was shut down by Warner Bros. earlier this month after a producer filed a complaint of misconduct following a sexual encounter between cast members Corinne Olympios and DeMario Jackson. Warner Bros. announced on June 20 that they had found no wrongdoing, and that Paradise would resume filming with new "policies and procedures."

Though Olympios and Jackson announced that they would not be returning to the show, the source tells ET that host Chris Harrison and producers spoke with the returning cast about how things would change moving forward, and that "the two drink per hour rule was put into effect, but people are still having fun."

As for the controversy, the source says that both cast and crew seem to be feeling good about how the situation is being handled, and that it was addressed from the start.

"The incident is being talked about on camera," the source revealed. "It has to be."
