There are a lot of Eye Tropes to indicate someone is going to cry. There's Quivering Eyes. There's showing the eyes welling up. There's the multiple blink-blink of blinking back tears. But there are also mouth cues to indicate someone is about to cry. There's the lower lip or chin quiver which is pretty much the same motion as a pout, but with the quivering in the lower lip instead of the eyes. The second is more common to animated fare, and instead of the lower lip quiver, their mouth is drawn as a single squiggly line to indicate someone is about to cry but is trying not to. And then there's biting or chewing on the lip. Seen It a Million Times.
