Was she stubborn or was she just plain stupid? Sorrel couldn't really tell, perhaps it was a little bit of both. Again she insisted on following him, his point of ignoring her and trying to turn away from her seemingly completely lost upon her. How hadn't she gotten herself killed yet, bugging and ignoring strangers wishes like this?
She would continue trying to get him to speak, her pleas practically acknowledging the very fact he was trying to prove; he didn't want to. A part of him was tempted to simply say 'hi' and then try to continue onwards, he'd have done what she wanted then after all. The grumpy gills comment and her sheer annoying factor however meant that his own stubbornness would continue and instead once more Sorrel would remain completely silent. Surely she had to get bored at some point. Meanwhile his thoughts lingered on how she was completely ruining his hunt for plants; it wasn't the easiest task after all with some idiot stalking and bugging you.
