Maelstrom hears the sounds of breaking glass and screaming wind. Horns blare and metal smashes. Inside the latrine, unfortunately, the commotion seems to have caused some kind of a surge and greeinsh liquid full of unspeakable chunks is jettisoning from the stainless stell seat right beneath him. Almost as distracting and slightly helpfully, paper towels are firing at his face with abandon as well.
And then as soon as it began, the sounds of mayhem ended. Outside the ship, a final dull thump rocks the plane and then all is dreadfully quiet.
NOnononononnonoNO! he is thinking. Not now! Not these people! No! I have to help!
Standing suddenly tall and resolute, eyes blazing blue, Maelstrom bursts through the door and yells, "Beware villain! You have attacked the wrong ship!"
He's been watching Cap and makes an effort at an impressive stance, hands on hips and legs spread wide. Unfortunately, it ruined by the sodden turban of paper towel and unmentionable streaking, but it was an effort. Kudos for that. He looked about and belatedly saw that the crisis was past.
"Eeep!" was all he could think to say and then he ducked back into the washroom and tried to close the broken door.
