Does Harrow even know there's stuff in her hair? All signs point to no, because skeletal hands aren't wiping at it, either.

"You have to demean the ritual, don't you," she sniffles, instead of returning the oath, because it is impossible to argue at this point that she's not dealing with Gideon, who she kind of wants to cling to and also cannot let herself do that because it is far too inappropriate, people could see it. Around the sniffling, though, she's smiling weakly. She even pulls her face back to look at Nav, so the cavalier can see her looking a combination of stricken sad and like she's going to laugh. "That makes you real. My mind wouldn't have the audacity to repeat that phrase twice."

It's almost as if she expects say it, loser to come next for some reason.
