Probably really excited. Like, little kid excited. He’s seen fireworks before, but not in the extent that you explained and that gets him really eager.
“AMERICAN CULTURE!”
Imagine sitting in front of the pond at Xavier’s, your feet dug into the grass below, and Kurt’s hand resting on your knee. It’s dark outside, and makes it hard to see his face, but you manage and give him a warm smile. The grass begins to tickle at your legs, and Kurt is humming a tune inside of his chest, trying to relax himself before the show starts.
Kurt giving you his jacket when he notices you shivering slightly. You return this gesture with a warm kiss to his lips.
Imagine the look in his face as the first firework is shot into the sky.
He looks like a little kid, and it warms your heart.
Pats your arm excitedly and says, “(NAME) LOOK OH! WOAH!”
Probably starts teleporting and bothers Peter, Scott, Jean and everyone to tell them about how cool the fireworks are.
Comes back to you and presses a kiss against your lips with a very soft, and gentle, “I really like fireworks.” and you just give him a cheesy smile and reply with, “Kissing you feels like a firework.”
Giving him a sparkler, and having him flip his lid because it’s so amazing and he just loves it and he ends up asking you for the entire box of sparklers(So he can use them any time he wants, which he does. He’s saving the last two for your birthday).
Alex Summers:
Is not particularly fond of fireworks. They trigger his PTSD, though he’s slowly learning ways to perhaps contain his outburst from the sound of fireworks.
This is something you completely understand and are supportive of. If, and when he’s triggered, you like to sing to him because the sound of your voice will bring him back to reality.
Though many people see the fireworks as celebration for freedom, which they are and Alex acknowledges that, he thinks that there should be an alternative, especially for those who have fought for that freedom, and do suffer from PTSD, and are sequentially triggered by the loud noises.
Tends to spend his Fourth of July, especially after 8 when the sun goes down, inside with you, maybe watching T.V, or snuggling, or taking a bath.
Really basking in the freedom that he has, and is thankful enough that he has you in his life to support him through things like this.
Peter Maximoff:
Let’s admit it here, he’s probably wearing leather pants that have the US flag printed on them(And he’s rocking them).
Really likes fireworks, and remembers going to see them with his mom and little sister before sticking around Xavier’s for a while.
Laying back in the grass in front of Xavier’s, his legs sprawled out and his head in your lap as you wait for the fireworks to start up. He gives you a cheeky grin, and shuts his eyes as your fingers run through his soft, silver hair.
The moment that the fireworks start though, Peter is wide-eyed looking at the sky.
Points out the shapes and colors to you, even though he knows you’re seeing everything he is. It’s a habit he has, for he did that with his little sister.
By the end of the show, he’s either A)Asleep with his head in your lap. or B)Kissing you and trying to entice you into a make-out session in the grass.
Lighting off your own fireworks.
Which he stole.
But, wouldn’t tell you that because you’d freak out.
You end up finding out any way and his excuse was, “WHY LIGHT OUR OWN MONEY ON FIRE?! THAT MAKES NO SENSE!” He’s shouting over the firework he just lit, giving you a cheeky grin.
This results in you threatening to shove a sparkler where the sun don’t shine.
