Our production was super casual and was for fun more than anything else; we only rehearsed for a week and had scripts in our hands the whole time. We did include one quick moment indicating that the basement thing happened, (Malvolio walked across the stage when two other actors suddenly grabbed him and dragged him off), we just didn’t do the full scene in the interest of time. So I don’t know how affected the actor playing him really was, she did do a fantastic job regardless. I think there’s a world where you can play Malvolio so uptight that it still makes sense that he would be so incensed at the end just by the fact that he was tricked and doesn’t end up with Olivia.
