Well, I think all of them would intervene!

A would likely stand in front of the child and face-off with the drunkard and very strongly suggest that they move along.

N would sweep up the child and take them somewhere safer.

F would make some intensely cutting remarks to the drunkard, possiubly commenting enough to confuse the drinkard, and then ask if the kid wants to go somewhere else.

M would be the simplest and just hit the drunkard…which N and A would just be tearing their hair out about in the corner, lol.

Thank you so much for the ask! :)
