Our volunteers look into many questions every day; sometimes it takes them a little while to answer.

Pro tip: you can rename the thread title with `.tr <thread name>`

Make it descriptive, including relevant context, but also to the point. This way you improve your chances of getting a more relevant and specific answer.

Je connais pas ce mot, effectivement le dictionnaire parle de maquillage. Je n’ai pas le contexte de la bd mais je pense que ça veut dire qu’il faut maquiller le monsieur de façon à ce qu’il passe pour un gaulois afin de s’infiltrer sans éveiller les soupçons. En gros faire en sorte qu’il ressemble à un gaulois

This is a case of ethical dative with -moi. It's to note a certain interest, involvement from the targeted person.
The sentence means something like "disguise him as a Gaul for me".

[icy drift]

Would the sentence still work without moi ?

Is the ça referring to the guy that has to dress up like a gaul?

[celest cradle]

Yes

In fact in his sentence, we detect a tone of mockery and sarcasm, he says « grimez-moi ça » as if it were an object
