After going through Wild Space, the Rebels’ ship is low on fuel as they ride on impulse power only. While they tried to find a place to refuel, they run into space whales called the Purgill as this fascinates almost everyone except for Hera. She isn’t fond of them based on her past experiences with them that their actions killed her friends. Ezra’s powers in the Force is growing as he senses a connection with them. Basically this was a filler throwaway that didn’t do much for anyone as there were no Imperials involved. An okay episode at best.
