"Simon felt it then, not the twinge of fondness he often experienced when Clary smiled at him, but a forceful rush of love that nearly swept him off his feet and into her arms. For the first time, he looked at her, and she wasn't a stranger, she was Clary--his friend. His family. The girl he'd sworn always to protect. The girl he loved as fiercely as he loved himself. 
 'Clary--' he said. 'When we were friends, it was great right? I mean, I'm not just imagining things, feeling like this is where we belong? We got each other, we supported each other. We were good together, right?' 
 Her smile turned from sad to something else, something that glowed with the same certainty that he felt, that there was something real between them. It was as if he'd switched on a light inside her. 'Oh, Simon,' she said. 'We were absolutely amazing.'" 
 This novella was mostly about Simon's character development than a story about the Herondales. But this is definitely something to remember for other books like Lady Midnight *wink wink*
