After some time in Annie's stomach, you begin to feel weak. While the gum base stands strong against the forces of digestion, all the other ingredients of your body are whittled away by the minute. Bright-red, flashing words appear in your mind, suspended before your eyes as clearly as if they were on a screen: "WARNING: Form integrity compromised! De-transformation impossible!" They blink at you a few times, but then disappear just as quickly as they started.
Cold fear, wailing regret, and hot anger all grapple for your attention in your metaphorical gut. How could you do this to yourself? Who was sadistic or stupid enough to give you the means to your own destruction? Your mind screams these questions to itself, because you can do nothing else but wait within your sister's literal gut.
