I do something similar at night time, requesting from 2 of them to go and spread anti-virus fields + some from the Alchemy of Love album.
I always feel lots of stuff in my hands lol, so with the servitors I rather ask them to tap on my forehead or squeeze my nose, whenever they want to say something like “mission accomplished” or “everything went fine Bron”.
And this is what happens when they are back from the virus-mission. I have faith in those dudes.
