We see Stede bumbling more than we've seen him in a while when he's fighting with Zheng, and with good reason, he's completely unequal to her, but I think it's more than that. We've seen Stede get out of sticky situations with some wily moves in just the right moment. There's a parallel with his duel with Izzy from S1 - in that fight, he was able to catch Izzy off guard and throw gunpowder in his eyes, but with Zheng, Stede's attempt at throwing dirt at her (?) is an abysmal failure. Nothing he tries works like it has in the past.
Earlier in the season Izzy says that he doesn't understand how Stede is still alive. Stede says he thinks he just works well under pressure. And we do see that's true in his "I did a punch" moment and with the immolation.
But when he's fighting Zheng, he is no longer so lucky. Later, he also tries to fight the English soldiers and needs to be saved by Zheng. At first I thought this was because he's so outmatched up against a pirate queen. He is, as Zheng pointed out, a mediocre man who thinks he's exceptional.
But I think something shifts when they get to the beach. Suddenly he's able to beat some of the British soldiers and hold his own against them. He's still no where near as good as Zheng, and he does need her to help him remove his sword from a soldier's body, but he got it in there in the first place and that's a big difference from how he was performing a few minutes earlier.
And I think what has changed in that moment is that Ed is nearby. Ed is returning to him. They're both on that beach and even before they're physically together, they know they are reunited. And suddenly, Stede is a better version of himself. He's a better pirate.
It might be that Ed's return has removed a weight of sadness and fear from Stede's mind. But I think it's also that he feels supported, and just having that support from someone you love (be it Ed, or the crew) makes everything easier. Makes it easier to be the best version of yourself.
Ultimately, this show is about love and about community and how much both matter.
