This guy is from France, currently residing in a British-speaking region. He's specifically from the city of Lyon, so I don't know if that influences something, like someone from Paris or Quebec have different accents from my research. What I want is some help in writing him, more specifically:

• How should I write his accent? Would he have any if he moved to this British region as a child?
• His manners, gestures, body language, should he talk in a certain way or have a different gait?

And anything else since I've just started building him.

I'm doing some research and found out a lot about stereotypes, but I'd like to have a solid base for him as in, not stereotyped facts. If anyone is French and wants to help I'll gladly accept (and if someone is from Lyon or knows someone who lives there, even better) :)
