In general there is like. a whole category of Voltron angst premises that utterly fails to make me feel anything because it often severely underestimates the strength of the characters that it proposes to be breaking.
Like… Listen. Lance pretty dang likely had internal injuries and had spent a pretty impressive amount of time unresponsive and he woke up like that and shot Sendak in the shoulder before nearly back out again. This tells us Lance woke up, probably in no small amount of pain, probably pretty loopy since he remembered absolutely none of it afterwards, and the absolute first thing that occurred to him to do is Sendak was right there and he had a clear shot so, fuck that guy. He got in that situation in the first place because he saw a bomb going off and his first priority was to protect Coran- who at the time he’d known for… days, maybe?
Pidge, the fourteen-year-old, who was pretty much entirely alone on the castle during that same time, having just lost contact with Allura, losing Rover and then hearing Shiro get tortured by Sendak- still kept her head about her enough to try and bait Sendak off with a hologram and was a major part of that fight. I mean. literally, take this emotionally compromised kid and go “you’re officially alone on a spaceship with murderous adult soldiers. They have your friends. They’re hurting your friends. You are the only one in position to do anything. Have fun.” And she won.
Keith had his shoulder hacked pretty impressively in the first room of the Trial of Marmora and was given multiple opportunities to bail with a pretty clear pattern that the next room would be worse and have more attackers and Shiro states it as a given that Keith will not give up. Kolivan unambiguously tells him going in this is a life-or-death scenario. This is also Keith who willingly soloed freaking Zarkon with Coran actively telling him that he had no chance of surviving that fight because Zarkon is not getting the Black Lion.
Allura destroyed the last thing she had of her father in order to protect her team and let herself be captured by Zarkon in order to protect Shiro. She caught her second wind and held out against Haggar as best as she possibly could even knowing those odds were not good.
Coran picked a fight with Zarkon’s entire fleet piloting a ship ten thousand years old, alone, and did pretty dang good.
Hunk actively, voluntarily, and enthusiastically picked a fight with a planet-eating monster stated to be one of the most dangerous things in space and long before that, all of his misgivings about signing up to save the universe evaporated like morning dew in the Sahara as soon as he saw what Shay and her people were going through.
A lot of “angst” content seems to really disrespect or even ignore that these people are fighters. Survivors. These aren’t people who flake under pressure. In Shiro’s case, he literally never would have made it if he was. We see that at his worst, during his missing year, when he was utterly baffled by the idea anyone would help him and was pretty unsubtly about to be knocked out and experimented on- he was full of fight. There wasn’t much he could do but he wasn’t going down easily and if nothing else, the fact that there were two good-sized soldiers in full armor in the room taking the role of sedating him would tell us that Shiro didn’t exactly obediently walk to that room in the first place.
I see a lot of stuff that acts like Lance could get captured and in the time it’d take the team to get to him he could be ‘turned to the dark side’ or broken as a person and it’s like… the empire had a solid year to work on Shiro when the latter had the assumption that no one who would want to help him would even have the technology to reach him or even know he was alive in the first place and the empire didn’t win. What honestly makes you think they could take a month and destroy any of the team?
