008. "Yes! Yes! Yes!" {Alec/Isabelle}

Somehow, the Lightwood siblings had been sucked into the most complicated love octagon this side of Gossip Girl. Magnus loved Alec loved Jace loved Clary who was loved by Simon loved by Isabelle and Maia, and it was all a mess. For as much as they fought demons, they sure had a lot of them. Simon and Clary had practically been raised as siblings, which didn't bother Simon; Jace and Clary were siblings, which tortured Jace but didn't actually bother him; and well – with all of that going on, who was to say that it should bother Alec and Isabelle?
