When Kanan and Ezra got back to chopper base with out Sabine, Hera freaked out. It took them a while to calm her down enough to explain what happened. Once they had told her she loaded everyone onto the ghost and went back to mandalor. Sabine wasn’t surprised that Hera showed up. She convinced Hera to go back to chopper base, because the rebellion needs you, but before she left she gave Hera a hug and said “I’ll miss you, mom."
