Spoof
Revali's physical wound heals with no issue. Despite being a more or less point blank blow from an arrow, the wound itself was fairly trivial. There is also no trace of the arrow, just some minor flesh damage under his feathers and traces of blood that has already dried.
Fred
Fred was quiet, watching with empathy from afar as Revali was being tended to. When he saw the healer's magic go to work, he had sighed with relief and began to munch on a red apple that he must have had on him.
When Revali gets up he watches him with the crossbow and smiles, happy to see the warrior on his feet again. He steps out to him about to offer some advice, “The trick to these contraptions is to…” but as soon as Revali releases the bolt he takes the brunt of the attack, screaming as the explosion sends him flying into the air.
The rest of the party is blasted away and the ship’s store of gunpowder ignites, severely compromising the upper decks.
Link
Link flies into the air with the explosion. He isn’t sure what has happened, he just feels the air then intense heat, then he is deep in the water, barely conscious.
It takes several moments before he even reacts, then he begins to float to the surface, watching the massive explosion from under the waves.
Irina
Maybe Irina is used to Revali shooting without thinking, and maybe that is why her instinct is to jump into the water as soon as the crossbow is aimed at the group.
The explosion catches her in mid air and she is thrown farther away and into the water. When she emerges, she widens her eyes in horror at the ship in flames and frantically looks around for her friends.
Redvali
"Felt worse? More like done worse..." Red muttered to himself. He steps away once Blue gets back onto his feet to give him some space. "As much as I'd like to stay grounded, I agree with myself. Ground or skies, usually it's the latter where we belong. I know you're concerned, but we should still play into our strengths," he states to Mipha, sharing the same sensibilities as his other half.
"Now that you're back, we should head out together so there's no chance of--" Unable to finish the sentence on account of the explosion, he's thrown away by the blast and arcs in the air coming back down in the water.
Mipha
"I don't want to keep you from the sky and that isn't my intention. I am keeping everyone together to minimize unnecessary risk." Mipha explained to Revali. "We already have crew missing and I don't want anymore, including us, to end up that way too." She watched him walk over to the recently loaded weapons and acquaint himself with one.
"Those are available to anyone that knows how to use one. I'm hoping they'll be useful for our predicament." She shared a soft smile, one glad to see him back on his feet and fussing in his usual way, but it quickly faded and was replaced with dread. She aimed her trident down at the deck and sent a jet of water from it to clear away from the area of the explosion just as it struck.
The force of it pushed against her, but she was able to right herself and dive into the water, escaping from injury.
Link
Link sees his friends appear above him, one by one, like drops of ink in the water’s surface. Irina. Fred. Red. Mipha.
An animal instinct takes over and he swims up to the surface slowly, powering through the pain that he can barely feel due to the shock he is feeling. He also doesn't hear anything from the explosion. He sees Fred floating down unconscious and he scoops him up, taking him to the surface. From there he looks around dumbfounded and overcome by disbelief. Revali was reckless but this seemed almost intentional.
Kala
At the time of the explosion, Kala was, luckily, relatively far from the group. Still, it sends her flying away from the ship and into the water, mostly unharmed but stunned.
Revali
Revali cleared away from the explosion easily enough, having taken flight no sooner than he'd launched the bolt. With the ship compromised, he begins searching the waters to find crew to pick off one by one.
"I need a report up here!" He called out, hoping for a response to narrow down a target. "Anyone?!"
Gatu
_Gatu was forcefully rendered unconscious from the explosion of the ship's gunpowder being accidently ignited by gods-knows-what, having been blasted and flung high through the air and landed several feet away in the water with a hard splash. He was close enough to where the blast that he was burnt and dealt second-degree burns to 19% of the left side of his face. The left sleeve and bracer of his tunic was basically destroyed, and clung to him barely by just a few meager ribbons. His left arm was sporting a baker's dozen of first and second degree since he was looking towards the right when the explosion happened._
Gatu
_The young man bobs and floats up and down in the cold water, which helped ease the burns that felt were biting into him, and slowly comes back to consciousness. Everything hurt and stung, his hearing was shot; with the only sounds he could hear was deafening ringing and the thrum of his heartbeat. He manages to swim over with his right arm to a half-burnt floating board, and grunts as he pulls his upper half onto it, but too tired to pull his lower half up onto it._
Gatu
_Revali or Redvali could probably see him down here from up in the air, or Mipha if she landed in the water like many of the others no doubt who were thrown off the boat violently..._
Irina
Irina cannot see those in the water yet. And the explosion just left her ears beeping for a while; she still can't hear anything. However, she can see Blue above her and waves, still looking very distressed from not knowing where everybody is—or if they survived the explosion.
Revali
Revali saw Irina's waving and flew down to hover nearby. "You managed to get away! Good. I'm not sure what I would have thought if you didn't. I...I didn't mean to..." He began. "I was just trying to get an idea of how it worked..." He sounded regretful. "The ship is in bad shape, but it looks like it's still floating. Do you need a lift over to it? Not that you would need my help. I think I've done enough damage already..."
Irina
Irina just hears parts of what Revali is saying but seems to get the idea. “It would be great if you could take me… Maybe we can spot everybody from there and see if we can help?” She is still very disoriented from what happened.
