Mr. and Mrs. Boom were two of my lowest-profile characters when I was ten. Mr. Boom feels embarrassed whenever he talks to his wife or whenever someone brings up her name.
But Mrs. Boom, on the other hand... she'll cast a spell on whoever Mr. Boom is arguing with. When the Booms are crawling their way out of trouble, Mrs. Boom likes to act as a shield for Mr. Boom.
Note: I thought up with those facts today. Super Arrow served as a source of inspiration for this blog.
