The vacuum created by a performer's absence leaves lots of room for questions, sure, but there seems to be an immediate jump to thinking the worst about a performer's character and talent that betrays a distinct lack of empathy. Empathy?! What about empathy for the people who travel a long distance or spend a lot of money just to see her? Any empathy by notifying what is going on? And it matters little if she's billed above the title, even if patrons get their money back, there is a lot expenses and time associated with attending a Broadway show, on top of the ticket cost.
Maybe she should show some empathy by communicating why she decided not to show up for work. At this point, it is obvious that everyone knows except the audience.
And if they decide to keep the understudy go on for weeks, we have all the right in the world to speculate whatever we want, as no one from her end has communicated anything.
Listen, I don't take my clothes off for anyone, even if it is "artistic". - JANICE
