Reached the episode where Edward and Ein leave the ship. It's the roughest part of every rewatch.
There are few scenes where Edward isn't smiling or making a goofy face in Bebop. But from the moment she sees that hologram of her father, and learns that she does have someone out there looking for her, that carefree disposition is gone. She more or less adopts Faye's crisis of not knowing where she belongs in life. Except that she's so young and has more time to create that path for herself. And she does so with more agency than anyone in Bebop.
That spinning wheel appears multiple times in this episode. I took it to represent that she is a free spirit. But that wheel can only spin if sustained by wind. With the crew, she is almost always idle inside of the ship while the others get to explore the world and do bounties. Often shown to be bored (with Ein), not allowed to do much for herself, though she is capable (as seen in Mushroom Samba where she and Ein solo a bounty). Ed gives that wheel to Spike before she leaves. And either Spike or Jet plant it onto the helm of the ship as it spins at the end of the episode.
Spike and Jet see Edward, Faye down after they return from the orphanage. They know something is wrong. But instead of asking them, maybe offering some sort of encouragement, they ignore them.
Then when they leave the ship, they're pissed. Those two stuffing eggs down their throats with frowned faces, zero communication, underlines so much about them as characters and their individual struggles (particularly Jet, who has lost relationships b/c of a lack of communication). They obviously care, but are too prideful to outright show that they care.
They still set up a bowl for Ed, even though they know she's left. Faye too though they swear to dislike her. And Ein, who was considered a burden by Spike in episode 2. That was the only family they had left and lost it all in one day, though Faye does return later.
It is Ein who shows the most compassion on that ship for the wellbeing of Ed, and it's an awesome moment when he decides to go with her. Though not before looking back at the ship twice, nearly turning around. In general Ein the most conscious character in Bebop, shown to understand situations better than any other human.
After the 2nd Vicious encounter, Ed asks Faye what happened in the arc with she and Ed left behind. Faye says she'll tell her when she's older. Too young to know what goes on in the world outside of the ship. So it's appropriate that Ed gets to find out what the world is like for herself, maybe later to meet Faye and Jet again and act as their peer rather than an oft dismissed underling.
There's voice actor commentary on the version I'm using. They give their thoughts on the episode in a casual manner. The staff really loved Ed and what she represented to Bebop. They were very emotional about her departure. The show treats her and Ein with really no less respect than Spike, Jet or Faye, which is probably the reason that most Bebop viewers appreciate those characters and respond as strongly to their departure.
