Depending on Andronica and Gamora's plans, getting Delilah into the Shadow World might be the initial plot point/catalyst.<br/><br/>If what they have in mind isn't suitable to throw the whole cast at, then I was thinking of throwing everyone at a suspicious cargo freighter that's dropped anchor in international waters. The Shadowhunters can take a boat out and investigate the spooky ship and see what's going on in there.
