My guess is Jodi has been holding back an anger outburst...got pale from holding her breath and biting her lip.... I quickly googled and found the following article:
HOW TO RESTRAIN YOURSELF FROM AN OUTBURST
<snipped for bandwidth>
Notice your emotional reactions and your actions. There are more giveaway signs of anger and a potential outburst shown in feelings and reactions. If you can learn to spot these, you can learn to quell your anger faster. Some of these may include:
Feeling upset, anxious, wanting to get away, sad, resentful, guilty, terrified, wanting to hurt someone or something and wanting a habitual relaxant such as a cigarette or alcoholic drink, even a prescribed tranquilizer you keep at hand and take at will; and
Actions such as pacing, rubbing your head, sarcasm, losing your sense of humor, becoming abusive or abrasive, yelling or crying, making a fist.
Physically restrain yourself. If you're speaking to someone and ready to burst, don't say anything. Hold your breath or bite your tongue if you have to.
If your anger is directed toward an object (like the above picture of a woman screaming at her cell phone) and you feel yourself about to throw it, hold your hand down with your other one.
Make a fist (don't let go of the object) and slam it against your chest or stomach if you have to (try not to be too hard, as you may hurt yourself).
If you're ready to kick someone or something, stomp on your foot and hold it there.
