I feel like Logan responds well to rewards, like imagine logan showing up to a party the x-men invited him and Wade to and they are really surprised about it and after awhile of asking logan only to get a grunt as response they turn to Wade and he pulls out this little bag with these treats in it and Wade hands one to them to try and they are surprised cause it tastes really good but then they are confused cause this didn't answer their question and Wade noticing goes "oh these are logans favorite snack I give him some when he does something with me as a way to tell him that I appreciate it and he's doing a good job" and then logan appears and Wade goes "peanut! There you are I've been looking for you" and then just hands him one of the treats to which logan visibly brightens up and eats it happily with a pleased rumble and the x-men are just left with more questions.
