Franco and Tinker actually interacted with each other as children at some point back in the day. Tink is 28, older than Franco. Tink's family moved from France temporarily to escape the war, they stay in Louisiana.
They always had a fixation for cards, but before playing poker, loved building houses of cards and setting up dominoes. So, Tinker was a kid minding their own business around the block and trying to build things. A little asshole like Franco who was already hostile at 12 and having issues at home probably got into a few afternoon scuffles.
I can see Franco destroying hours worth of domino set ups or card builds. Maybe stealing toys and trinkets as well like the brat he is. Foolishly creating an enemy instead of a friend. The family moves away eventually, and if i can imagine the timeline correctly, they dont see each other again from the time they are about early teenagers until meeting up at Sinyala.
Now, Franco forces Tink to sit strapped to traps and deadly life threatening contraptions while they play shitty rigged card games. (think RE7 lucas) Franco cheats every time because he is always losing every time. Tinker is naturally gifted with luck, which is why they're reagent 777. Also Franco has no hold against the insults Tinker can throw at him.
Guards. Roast him in french.
