Please, they planned this fight so that Olivier could make a citizen's arrest. Gabriel's in the US on a work visa, if he's arrested, the visa gets cancelled and he goes back to Canada, which means he will not be able to see Nahla.
It's not a coincidence that this all happened mere days after a judge rejected her request to move to France. She wasn't successful in leaving the country, so now she's trying to get him kicked out of it.
I believe it. She sounds like a box of crazy. And IDK if Gabriel started it or not (convenient that there wasn't any surveillance video after all) but his face has been destroyed. I cannot see where she gets off saying he's not safe for their daughter but Martinez is after doing something like that to another man.
