According to the synopsis of the episode, on a mission to escort a courier with secret information vital to the rebel cause to a rendezvous point, Sabine must face off against her old friend and partner.

It seems that the rival knows a lot about Sabine that confirms the fact that she is not a stranger.

According to the previous episodes, there is a probability that this new enemy is none other than Ketsu Onyo, a Mandalorian bounty hunter and an old friend of Sabine.

In previous episodes, Sabine and Ketsu parted ways because of Ketsu's illegal activities that were constantly disapproved of by Sabine.

However, despite Sabine's constant persuasion, Ketsu never listened to her and finally managed to fall into the trap of the rebel police who imprisoned her.

It has been a long time since they saw each other. Though Sabine is not sure that it's Ketsu, she suspects her enemy is Ketsu because she has many gestures similar to Ketsu's.

In the previous episode titled "Wings of the Master," Phoenix Squadron was travelling through hyperspace and was on its way to Ibaar where people needed aid in distress.

The Empire had cut them off from the outside world and had also restricted their ration supply.

At the end of the episode, Commander Sato complimented Syndulla for her heroic acts and promoted her to Phoenix leader, as recommended by Jarrus.

Besides, Hera thanked Quarrie for helping her save the people of Ibaar. However, Quarrie said that it was actually Hera's victory as she was the one who navigated the ship.
