Very nice. I did find it a little amusing that the battle, as big as it was, was almost treated as a prelude to whatever might happen in Season 4. I mean, Hornigold, Scott, Vane, and that guy whom Billy's group killed are dead. Pretty much all of the other important players on both sides are still around. That council of...five? Yeah, that might not hold for long. And do they plan on still using that island as a base?
I kind of liked how the talk between Flint and Silver was spread out through the episode, as if that was the crux of the episode as opposed to the battle. I did find it a little odd that they skipped over Flint telling Silver about his relationship with Thomas and went right to the fallout. On the other hand, I did not mind the more "tell" aspects of it. Silver's insistence that his men would not betray him framed that sequence leading to the ambush in a different light, less of a "will he/won't he" and more of a how. And all that stuff about Silver noting a pattern and refusing to be part of it was just his laying his cards on the table. While he may have tried doing stuff behind Flint's back before and may do so in the future, I think that he respects Flint too much now to pretend that their relationship will not be tested and be found wanting. And I think that Flint may not have liked what he heard, but he at least respected Silver for not lying to him about it.
Actually, the whole back and forth reminded me a bit of the Red Cliff movies, even though it is not quite the same. The two protagonists were military leaders of two rebel groups and formed an alliance to repel the Empire. They also formed a pretty easy-going friendship, based on respect for each other's character and strategic intelligence. Throughout the movie, however, they each casually alluded to the distinct possibility that they would end up on opposite sides of a conflict in the near future. According to the histories, the two actually would become bitter enemies, and the audience is expected to know this going into the movie. The movie, however, ends long before this happens, with them bidding goodbye not just to each other, but also to a friendship that was genuine, if only temporary. It is as if that they knew that it would not last, but instead of that knowledge keeping them at a distance to each other, it brought them closer, as if this is something that should be cherished before it is destroyed. So...yeah, not quite the same, but it did remind me of that.
