I Don’t Do Any DIY

In season one, Ed says with anger, "We raid, we steal, we're onto to the next, it's all so fucking boring" and then in s2 with tears in his eyes he tells Frenchie, "We'll raid, we'll steal, we'll move onto the next, for ever and ever" and you can feel the sense of hopelessness that he's dealing with. But this time, it hurts more because he now knows what it feels like to be happy, to be excited about life, about not knowing what's next. He's experienced it with Stede and there wil never be another Stede. So he's really doomed to the ocean forever, just as he thought back in season one. This day, this version of Blackbeard, was gonna come eventually.

Keeps rrying to escape back to the sea, had to be restrained until further notice

this might be relevant again

stede saying "i'm afraid to see you. i'm afraid that your life is better without me" when ed is literally ending his life because he's lost the hope stede brought into his existence...stede being the light in ed's darkness...stede begging him to live and showing ed he matters and he is loved and someone out there believes in him and wants him around...i'll be here cryin all day lads
