Okay, so we have a standard SickEpisode. So far, Alice has started periodically doubling over with a pain in her abdomen. The audience knows where this is going. More likely than not, this will end with a RupturedAppendix.
But when Bob notices Alice doing this and asks her what's wrong, she says it's "just a stitch". She might actually believe this, or it could be done in an effort not to worry him. Often he'll believe her until it becomes obvious that it isn't so minor.
