What are they talking about? You allow them to whisper in your presence? Erik wasn't pleased with being left out of the conversation, but Bran knew he was an outsider - not to mention the fact that depending on what Lotte told her, James could have been five seconds away from trying to kill him with her bare hands. He could easily subdue her, but really, he'd rather avoid the extra effort.

If she was anything like Christine, though - which she was - then she wouldn't keep it to herself. He and Erik couldn't trust Lotte and Christine any more than the women could trust them.

Finally having silenced him, Bran cleared his throat and approached the pair. "We shouldn't linger in the streets too long. Supplies will become harder and harder to find, especially water."
