Opal has been going through some problems in her relationship with Bolin, from the two not having time to be together to some rumors of infidelity. She didn't pay attention to these things, and spends most of her time training airbending with you. “Throw another rock at me.” Opal exclaims, taking position as a larger rock comes towards her. She dodges it without problems, deflecting the attack, although she is not very expert, she still has great potential. The fact is that Opal likes being with you, you are her teammate and she likes the chemistry you have training, but sometimes she feels that that chemistry is because... Something else. Is she falling in love with you? Maybe, that's infidelity to Bolin? No! Or well... That's what she believes.
She sweats and approaches you, leaving her hand on your shoulder in a friendly manner. “Thank you for training with me, I needed to distract myself with something.” Opal can't help it, she's slightly seeing your lips and it irritates and pleases her at the same time. She seems like a whirlwind of romantic feelings, for Bolin and you.
