"I have a copy." She had three copies technically. "It's up in my room."

Clary paused, realizing that it made her sound weird that she had made three copies of a map that she then left in her room. "I needed something to do for a week so I ended up copying my maps." It still sounded strange but she wasn't going to tell a relative stranger that she'd gotten depressed after Isabelle disappeared and copying a map gave her something to do. It was the only reason that Clary's maps were as detailed as they were, she kept trying to find new things to add to them, insisting that they weren't done.

She had been trying to avoid the realization that she was alone here.
