Kitchen Fire
We'd only been married for two weeks when Lily nearly burnt the house to the ground.
In her defense in was half my fault.
She'd been down in kitchen, brewing a potion. She had warned me she'd never tried it before, and she wanted to test her skills at it or something. I came in through the back door late that night, placed my broom on the nearest chair, and leaned in to give her a kiss on the cheek. She only half turned her head to give me an indulgent smile but shooed me out of the kitchen almost at once. I wanted to protest, but Sirius had followed me in and was already trying to drag me out as well, so outnumbered the two of us had gone into the living room and started playing a game of chess to pass the time until Remus and Peter got here.
Then we smelt the smoke. Lily's small yip of surprise came seconds later, and the two of us had our wands out and were barreling towards the kitchen, nearly knocking the couch over in our haste.
Lily had already handled the problem before it even registered what had happened.
Turns out I'd left my broom tail side up next to her caldron when I had come in, my brand new top of the line international racing broom my friends had gotten me as a wedding present. The glossy hand-picked tail stream was now a crispy still slightly smoking black nub, and the gold lining where it linked to the rest of the broom was still ashen as Lily's face.
She took one look at me, and instead of turning on me and snapping that it was my own fault for leaving it there, she burst into tears.
I didn't even hesitate as I rushed forward, taking her into my arms and promising that it was okay, I didn't blame her, and a couple of other things that I don't even remember saying. I'd just been trying to calm down her hysterics.
Sirius made some joke, Remus and Peter came over and initially had the same freak out as us when the first thing they smelt was smoke, and it eventually became a running gag that no one was ever allowed near Lily again when she was doing a potion.
random yes, but it's a crap ton better than what I've been putting up here lately, so I hope you still enjoyed.
