no, she has discussed her distaste for guys hitting on her in the less subtle ways college guys are known for, and has expessed hollywood romance as unrealistic. she likes Princess Bride as a story, but she only really likes the typical romance of it because te typical romantic kiss isnt from two people who just met on this adventure, but because it was between two people whos romance was already established, was described to have developed slowly over time, and the final kiss was the result of a reunion, unlike other typical romance stories.
thats why even if that glance meant more than just two people looking over at the same time, i doubt that was an invitation to a kiss, based on our previous discussions of The Princess Bride and other romantic movies.
