Sadly the gamble you take with any live show. You never know though, often the understudies are v good.
Very true, and it's why understudies are there in the first place. I remember that Wicked had a much more serious version of this at the very end of Idina Menzel's run; she actually was injured in her fourth-to-last show and couldn't perform for what was supposed to be her last three except for a cameo at the end of the final one.
