I agree that Sabine using the force to push Ezra is too much, but I disagree that she shouldn’t use the force at all and that the series has consistently shown this. Some people are misremembering Rebels. It was never stated by anyone that Sabine was unable to use the force. In fact, Kanan only said that anyone with enough practice could use the force and that Sabine couldn’t do it because she was emotionally blocked because she felt betrayed by her family, and then in the very next episode they go and resolve that issue but then Sabine leaves the show for the rest of season 3. She was never stated to be unable to use the force or having no potential in Rebels. Also throughout the entirety of Ahsoka, she was only stated to have the worst potential Huyang had ever known, but it was never stated she had no potential. Also in Ahsoka, we see her practicing all season and basic storytelling conventions should tell us that by the end of the season, Sabine should use the force, and she does. The only issue though is her being able to push Ezra. I have no issue with her using the force to grab the lightsaber as that’s a smaller feat and both Luke and Rey are able to do that without much training so it makes sense that Sabine needs to use tons of training to just be able to do that. It’s just that pushing Ezra is a bit too far. I get what they were trying to do, they were trying to show that Sabine could use the force but was just blocking herself and that after she uses it to get her lightsaber her block is gone, but the two events still feel way too close together for it to be believable.
I don’t disagree with the idea of someone with absolutely no talent with the Force managing to attune themselves enough with training and practice. I just think it should be much more of a struggle than this show presents. Maybe by the end of this season, the most Sabine can do is barely nudge that cup but she’s able to sense other people and has quicker reflexes.
I actually think we got a good example of a really spiritually Force-attuned person with no actual talent in the Force: Chirrut Imwe in Rogue One. Sure he couldn’t Force push or jump high, but he had impressive reflexes and martial skills and by the end, his trust in the Force was so strong that he dodged blaster fire long enough to save the day. I don’t think any of us disagree he’s the closest to a real Jedi that a non-Force sensitive could become. I think Sabine should have been something similar, something different from “normal” Jedi but no less valuable in that way.
