"They're..."

Marinette wasn't entirely sure how to describe it, but she could darn well try. After eighteen years of watching them, hopefully she'd manage.

"They support each other," she said after a moment. "No matter what. Maman's always been good at encouraging him to do his best. And Papa's always there to encourage her to try the things she's always wanted to try."

Another pause, and then -

"...they're partners."
