This lady's name is Megaera, Meg for short. She is one of the three Eumenides sisters, originally from Thessaly in northern Greece, once described as the 'personification of curses pronounced upon the guilty'.
The gentleman is showing great presence of mind at this time of seasonal tribulation. He is holding fast to that which is good.*
I don't know what he did or said to light Meg's ire. Something trifling, to be sure. I'm afraid I was under the table at the time.
