You Are Doing Fine
Sierra held Odette's shoulder firmly and scanned her from head to foot like an estranged mother surprised how her daughter had grown, "Are you alright?" She gave her a wistful look and I can pretty much see that Odette is trying her best not to cry but she failed to do so since a bead of tear escaped her left eye which she was quick enough to wipe it away using her hand.
I believe it was so hard for Odette so speak when she is trying to prevent herself from crying. I myself experienced forcing myself not to cry. It is the clenching of the jaw and tightening of the throat, the burning sensation in the eye from the tears that has been held out for too long. The answer to Sierra's question was an obvious no, I cannot understand why she even asked it in the first place. Anyway, Odette refrained from crying making her contort which makes it look like it has contorted.
