“Destiny, with its mysterious and fatal patience, slowly drew together these two beings, all charged and all languishing with the stormy electricity of passion, these two souls which were laden with love as two clouds are laden with lightning, and which were bound to overflow and mingle in a look like the clouds in a flash of fire. The glance has been so much abused in love romances that it has finally fallen into disrepute. One hardly dares to say, nowadays, that two beings fell in love because they looked at each other. That is the way people do fall in love, nevertheless, and the only way.
The rest is nothing, but the rest comes afterwards. Nothing is more real than these great shocks which two souls convey to each other by the exchange of that spark.
At that particular hour when Cosette unconsciously darted that glance which troubled Marius, Marius had no suspicion that he had also launched a look which disturbed Cosette.”
