I mean, hes an artist, a poet, a fighter, a genius, a language expert ect. Joe is pretty much good at everything and we love him for it. However maybe there is ONE thing hes just terrible at (I actually have no idea what this could be so am open to any and all suggestions) and whatever this skill is, its required for a mission. Cue Nicky getting literally turned on to see his usually cool and competent husband adorably frustrated and flustered by being so terrible at something.(and giving him a way to work those frustrations out)
