Reed is a good choice for the finale... but he directed probably the weakest episode of the season. Although in his defense, he wasn't given a ton to work with in that episode and I'm assuming he's going to be working with an action-packed episode here. I remember hearing Giancarlo Esposito saying at one point that he broke multiple lightsabers on set while shooting the season and we've yet to see him in combat this season.
As far as what I hope for the finale, I do want an episode that's pretty close to an hour (and I think for a finale it should be worth it). But overall, I just want a really good season finale. I'm going to guess that Din doesn't get Grogu back by the end of the episode, Ahsoka and Bo-Katan show up and Bo ends up with the Dark Saber somehow. Idk if we'll see Moff Gideon die or not. If so, we'll almost certainly see a Thrown tease at the very end.
