He's a Keeper

Marinette?

Adrien walks into the ballroom. He scans the dancers for Marinette. His eyes land upon his aunt Tanya emerging from a hallway instead.

"Where's Marinette?" he asks her, concern plain on his face.
She grabs his arm and pulls him along to dance to the next song, an upbeat circle dance.

"Oh she's fine." Tanya says, swinging to the beat. "I mean she said she wasn't feeling well and I took her to the bathroom."
She turned on him, eyes mischievous, "Should I be expecting a mini Adrien soon?"

Adrien blushes, but doesn't reply as his father appears. "I should hope not," the elder Agreste answers. "From what I know, you two aren't married or engaged."

Adrien shrugs. "No father, not yet at least"

Gabriel Agreste nods, then disappears, leaving the two to talk privately once more.

"So Aunt Tanya, which bathroom is Mari in? I'll go check in on her if you don't mind me leaving you here."

His aunt grabs his arm. "Adrien I haven't seen you in so long. Your girlfriend's not as weak as she seems she can last a couple minutes without you."

Adrien nods absentmindedly, "just one dance."

Three dances later Adrien finally manages to tear himself away from his aunt. He heads towards the hallway he saw her coming from when Tanya grabs his arm again. 

"Adrien, hide!"

"What-"

The crashing of tables stops his words.

Tanya gasps. Adrien follows her eye line to a taller-than-usual feminine figure. She wears wedding attire from head to heel. White flats, a white dress with a white veil. The whole works. The only splash of colour is the bouquet she wields. It's a red polka-dotted rose arrangement.

Adrien looks at her face. The lady had blue eyes, lots of freckles and hair that seemed almost blue in the lighting.

"I AM JOLIE CASAMIENTO, NO ONE CAN TELL ME I DON'T LOVE AND CHERISH ADRIEN AGRESTE. NO ONE CAN TELL ME I WON'T MARRY HIM ONE DAY. NO ONE CAN TELL ME I'M NOT GOOD ENOUGH FOR HIM. NO ONE CAN. NO ONE!!!!!"

Marry him?

No it couldn't be ...

"Marinette?"
