But when they returned and Sam found out about the news, he had a really hard time telling Andy. Still, she noticed he was being weird once they returned from their three week getaway. But she also realized Marlo wasn’t being herself either; making her think there was a connection between both.

“Then what? Is it Marlo? Is she sick or something? Off her meds? She’s been acting strange lately.”

Before Sam can reveal what’s really going on, an intruder they were looking out for is spotted so their conversation has to wait. Before that Sam was about to tell Andy when they were on the phone, but Andy was attacked by the intruder in her home. So he rushed over to try to catch him. The two had finally gotten on good terms and comfortable with one another. In fact, Sam had just asked Andy to move in with him in the season 5 finale. But now their relationship has been rocked by Marlo’s news. See if they’ll be able to overcome it when Rookie Blue returns to ABC Thursday, June 25 at 10/9c on ABC.
