I love it when not only are there great costumes but the cosplay to go along with it. These two introduced themselves with blasters pointing and "Have you seen an R2 unit go by."
After checking my credentials for making a holovid of them only the stormtrooper would reveal his identity TK6441. As expected the Mandalorian was surly and silent.
Not in the picture is a real nice mic unit set up in the armor for the trooper inside to speak through.
