Prompt: Are the rumours true? After x-decades of marriage, a flock of kids and grandkids, and a receding hairline later, Marcus Flint is convinced that he's losing the love of his life to his archnemesis, the newly widowed/divorced/single Oliver sodding Wood.
Suggested Characters/Pairings: Katie Bell/Marcus Flint, Oliver Wood
Theme/Tone: humorous, fluffy
Additional Info: I'd like to see how Marcus goes about finding out the 'truth', maybe some memories of the past thrown in. Maybe, he recruits his (grand)kids to do the dirty work for him. Please, no actual infidelity. HEA is very much appreciated.
